Why it matters
Power is the foundation everything else in the system depends on.
Modern power design balances efficiency, noise, size, cost, and thermal performance all at once. Switching supplies are efficient but generate noise; linear regulators are quiet but dissipate heat. The art is in selecting the right topology and implementing it correctly for each application, whether the load is sensitive analog that demands ultra-low noise, digital that needs fast transient response, or a high-power stage that has to manage significant heat. From DC-DC converter and power supply design through to battery management system (BMS) and wider power electronics design, the aim is a rail that stays clean and thermally safe under the worst-case load, not just on the bench.

How it works
A clear path from requirements to a verified power stage
1
Requirements analysis
I define input voltage range, output voltages and currents, efficiency targets, noise requirements, and environmental conditions, then identify the critical constraints driving the design.
2
Topology selection
I select the optimal converter topology (buck, boost, buck-boost, flyback, and so on) and weigh the trade-offs between synchronous and non-synchronous designs and integrated versus discrete solutions.
3
Component selection
I choose the controller IC, MOSFETs, inductors, and capacitors for the performance you need, and verify every component rating under worst-case conditions.
4
Design and simulation
I complete the circuit design including compensation network, protection circuits, and filtering, then simulate to verify stability, transient response, and efficiency.
5
Verification
I prototype and bench-test to validate efficiency, transient response, thermal performance, and EMC behaviour, iterating as needed to meet every requirement.

Questions
Frequently asked
What power electronics do you design?
DC/DC converters, LED drivers, low-noise and low-ripple supplies, battery and charging circuits, and higher-power stages with proper thermal management.
How do you handle efficiency and heat?
Topology and component choice set the efficiency, and layout sets how well the heat and switching noise are managed. I size copper, thermal paths and filtering for the real load and verify temperatures on the bench.
Can you design a low-noise supply for sensitive analog or RF?
Yes. Quiet power is often the difference between a measurement that works and one that does not, so I design the supply around the noise budget of the load.
Do you take it to a tested prototype?
Yes. I build and bench-test the board, including load and thermal checks, so the power stage is proven before production.
Do you design battery management systems and DC-DC power supplies?
Yes. Battery management system (BMS) design, DC-DC converter design, and general power electronics design are all covered, from cell protection and balancing through to the switching supply, its layout, and the thermal path, so the design holds up under real worst-case load rather than only at nominal.
