Power Electronics Design Services

We design circuits for various types of power supplies including linear regulators, switching regulators, precision voltage and current regulation, power over Ethernet (PoE), isolated power supplies, hot-swapping and redundant power systems.

We use different semiconductor devices for different types of projects. MOSFET and IGBT are the most common solutions that are widely used in power electronics development. For high-power systems, we prefer GaN which provides a high level of current, switching frequency, and working voltage. It also has a low channel resistance. All this contributes to the efficiency of the power electronic device.

We work with Li-ion, LiPo, LFP, NiCD, Ni-Cad, Ni-MH, and lead-acid batteries. Every battery chemistry has its own characteristics, so we use them in different projects for different purposes. Thus for consumer electronics and portable devices, it is better to use Li-ion, LiPo while Ni-MH batteries are a great choice for systems operated at very low ambient temperatures.

The biggest issues that we face during the design of power electronics are heating of the hardware and the high level of electromagnetic interference (EMI). To avoid such issues, our power electronics engineer optimizes the overall efficiency of the system to provide heat dissipation and employs EMI filters to block the emissions.

Testing of power electronics circuits involves our standard hardware verification procedures, including ERC, DRC, electronic circuit simulators, electrical tests, etc. It also includes a load test when the circuit is tested under actual and extreme operating conditions. Thus, the device is exposed to both regular and extreme temperature, input voltage range, and output power.
