High-frequency power inverters utilize high-speed switching at frequencies significantly higher than the standard 50/60 Hz grid frequency. This article provides an overview of high-frequency inverter topologies, design considerations, applications, and advantages versus traditional lower frequency inverters.
In today''s world, inverters play a vital role in various applications, such as home solar power system, inverter for office use, inverter for van, etc. Central to their operation is the concept of an inverter frequency, which determines the rate at which the current alternates direction.
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:
Salient characteristics of high-frequency inverters: Some benefits of high-frequency inverters compared to line-frequency inverters operating at lower switching frequencies: Size reduction – Components are much smaller due to high frequency. Weight reduction – Lower weight allows increased portability.
