Most people think about electricity in terms of generation.
Power electronics is about control.
It converts, switches and regulates electrical power so batteries, motors, chargers, data centres and industrial systems receive electricity in the form they actually need.
Did you know that Singapore’s 2026 semiconductor strategy created a new national power-electronics platform focused on silicon carbide and gallium nitride?
This article targets the search ideas power electronics Singapore, silicon carbide Singapore, SiC semiconductor Singapore, gallium nitride Singapore and wide bandgap semiconductor Singapore.
Official information was checked on 4 October 2026. Worked examples are fictional.
Did You Know? Singapore Is Investing S$60 Million in a National Power-Electronics Centre
A*STAR announced in March 2026 that Singapore will invest S$60 million to establish the National Semiconductor Translation and Innovation Centre for Power Electronics.
The programme focuses on silicon carbide and gallium nitride technologies for scalable manufacturing and commercialisation.
Official reference: A*STAR — Committee of Supply 2026.
What Is Power Electronics?
Power electronics controls the flow and conversion of electrical energy using semiconductor devices.
It converts AC to DC, DC to AC, changes voltage and controls motors.
The technology sits inside EV chargers, renewable-energy inverters, industrial drives, consumer electronics and data-centre power supplies.
It is the traffic-control system of electricity.
Why Traditional Silicon Is Not Always Enough
Silicon remains enormously important.
But high-voltage, high-frequency and high-temperature applications can expose its limitations.
A*STAR identifies silicon carbide and gallium nitride as wide-bandgap materials that can enable smaller and more efficient power systems.
Official reference: A*STAR — Semiconductor Industry.
What Is Silicon Carbide?
Silicon carbide, or SiC, is a wide-bandgap semiconductor material suited to high-voltage and high-temperature power applications.
Its properties can allow power devices to switch efficiently at higher voltages and temperatures than conventional silicon in suitable applications.
That can reduce losses and shrink cooling requirements.
What Is Gallium Nitride?
Gallium nitride, or GaN, is another wide-bandgap semiconductor.
GaN can switch very quickly and can support compact high-frequency power electronics.
It is also important in high-frequency RF applications for communications and radar.
SiC and GaN overlap in some markets but are not identical substitutes.
The New Singapore Centre Includes an Open-Innovation 200 mm SiC Pilot Line
A*STAR states that NSTIC Power Electronics will house the world’s first open-innovation 200 mm silicon-carbide R&D pilot line.
The platform is intended to support rapid prototyping, industry collaboration and technology transfer toward manufacturing.
Official reference: A*STAR — NSTIC Power Electronics Factsheet.
Why 200 mm Wafers Matter
Larger wafers can fit more devices per wafer, subject to die size and process yield.
That can improve manufacturing economics when the process is sufficiently mature.
Moving a material platform to larger wafers is therefore not just a scientific milestone.
It is part of scaling the technology toward industrial production.
Worked Example: Efficiency Loss Becomes Heat
Imagine a fictional 100 kW power converter operating at 95% efficiency.
It loses about 5 kW as heat.
At 98% efficiency, losses fall to about 2 kW.
The three-kilowatt difference affects cooling, enclosure size and electricity consumption.
A small percentage improvement can matter enormously when power levels are high.
Electric Vehicles Are a Natural Application
EVs need power electronics for battery charging, motor control and voltage conversion.
Higher efficiency can extend driving range or reduce cooling burden.
Faster switching can help shrink passive components.
The value appears at vehicle-system level, not merely at transistor level.
Data Centres Need Efficient Power Conversion Too
AI servers consume enormous electrical power.
Electricity passes through multiple conversion stages before reaching processors.
Losses at each stage become heat that must be removed.
A*STAR specifically identifies data-centre energy reduction as an application for next-generation power electronics.
Official reference: A*STAR — COS 2026.
Renewable Energy Needs Inverters
Solar panels produce DC electricity.
The grid and most buildings operate with AC.
Power electronics converts and controls that energy.
Grid-scale batteries also need bidirectional conversion.
See Making Singapore Rich | Solar Energy, Energy Efficiency and Clean Technology.
Industrial Motors Are a Huge Efficiency Opportunity
Motors drive pumps, fans, compressors and production equipment.
Variable-speed drives use power electronics to control motor speed according to actual demand.
Running a motor only as hard as necessary can reduce wasted electricity.
Power electronics therefore connects directly to industrial energy productivity.
Worked Example: Switching Losses Accumulate
Imagine a fictional converter loses 20 joules during each switching cycle and switches 10,000 times a second.
That would imply 200,000 joules per second, or 200 kW of switching loss—a clearly impractical design.
The numbers are intentionally exaggerated to show the mechanism.
Fast switching becomes useful only when device and system losses remain controlled.
GaN Is Also an RF Technology
A*STAR’s NSTIC GaN facility supports GaN platforms for high-frequency communications, radar and satellite systems.
The centre opened in 2025 with 6-inch GaN-on-SiC and 8-inch GaN-on-silicon fabrication capability.
Official reference: A*STAR — NSTIC GaN.
This means GaN sits across both power-electronics and RF technology domains.
Packaging Is Part of Power Performance
A high-performance semiconductor die can be weakened by poor packaging.
Electrical resistance, thermal paths and interconnect inductance can reduce system performance.
Wide-bandgap devices therefore create opportunities in advanced packaging and thermal engineering.
See Making Singapore Rich | Advanced Photonics, Integrated Optics and Laser Systems for another example of packaging determining system performance.
Reliability Is More Important Than Laboratory Peak Performance
A device can demonstrate excellent efficiency once and still be unsuitable for long-term industrial use.
Customers need lifetime, thermal-cycle and failure-mode evidence.
Commercialisation therefore requires reliability engineering alongside device physics.
The best benchmark is not the most impressive one-time measurement.
It is dependable performance over the intended operating life.
The Risk: Wide-Bandgap Devices Cost More
SiC and GaN devices can cost more than silicon alternatives.
Their value depends on system savings in efficiency, cooling, size or performance.
The business case should compare total system cost rather than semiconductor price alone.
The Risk: Faster Switching Creates New Engineering Problems
High switching speed can reduce some losses and component sizes.
It can also increase electromagnetic interference and make layout more demanding.
Power electronics rewards system engineering, not device substitution without redesign.
The Risk: New Materials Need New Manufacturing Know-How
SiC wafers, epitaxy, defects and processing behave differently from silicon.
Scaling manufacturing requires specialised equipment and process control.
The new national pilot line is designed precisely to help move technology from research toward manufacturable processes.
Power Electronics Connects to Singapore’s Semiconductor Base
Singapore already has major semiconductor manufacturing, R&D, packaging and testing capabilities.
Power electronics extends that base into electrification markets.
See Making Singapore Rich | Singapore Semiconductor Industry.
Power Electronics Connects to Precision Engineering
Packages, substrates, thermal interfaces and test equipment all require tight tolerances and reliable materials.
See Making Singapore Rich | Precision Engineering and Industrial Metrology.
Education Builds Wide-Bandgap Capability
The field combines semiconductor physics, circuits, control theory, thermal engineering and manufacturing.
Engineers must understand both the device and the system around it.
See Making Singapore Rich | Education, Skills and Human Capital.
A Guided Classroom Investigation
Give students two fictional power converters.
Converter A is 95% efficient and costs S$1,000.
Converter B is 98% efficient and costs S$1,600.
Ask what electricity use, operating hours and cooling costs are needed before deciding which is economically better.
The lesson is total lifecycle cost.
Independent Practice: Device or System?
A new semiconductor switches twice as fast.
Ask students whether the final product will automatically become twice as efficient.
They should identify packaging, control, thermal design and circuit topology as additional variables.
The learning goal is system thinking.
What Progress Should Look Like
A stronger power-electronics economy should produce more wide-bandgap R&D, reliable SiC and GaN devices, advanced packaging, power-conversion products and skilled jobs serving EV, data-centre, industrial and energy markets.
A stronger learner should distinguish semiconductor performance from system performance, efficiency from purchase price and research capability from scaled manufacturing.
