Optimize based on tradeoffs. Filter components – Smaller inductors and capacitors possible at high frequencies. Balance size versus performance.
How does a high frequency inverter work?
The inverter bridge contains power switches like IGBTs or MOSFETs. The switches turn on and off at high speed to generate high-frequency pulses. An LC filter smoothens the pulses into sinewave AC output. The output frequency depends on how fast the switches cycle on and off. Common high-frequency inverter circuit configurations include:
What are the topologies of high-frequency inverters?
