Apr 1, 2023 · This application report documents the implementation of the Voltage Fed Full Bridge isolated DC-DC converter followed by the Full-Bridge DC-AC converter using TMS320F28069
The high voltage frequency converter integrate the most advanced motor vector control algorithm, high control precision, fast response, low frequency, high torque. Our high frequency power inverter can be applied to energy-saving speed regulation and process improvement of high-voltage asynchronous motors and synchronous motors.
The output frequency of the high-frequency inverter is much higher than the power frequency, usually between a few kilohertz and tens of kilohertz.
Common high-frequency inverter circuit configurations include: Key design factors for high-frequency inverters: Switching frequency – Higher frequency allows smaller filter components but increases losses. Optimize based on tradeoffs. Filter components – Smaller inductors and capacitors possible at high frequencies. Balance size versus performance.
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:
High-frequency inverters operate from around 10 kHz up to 1 MHz range, far higher than 50/60 Hz line frequencies. RF inverters can reach up to 30 MHz range. What are some common semiconductor devices used in high-frequency inverters?
Due to the use of high-frequency switching technology, high-frequency inverters have the advantages of small size, lightweight, and high efficiency, but they also have the problem of relatively poor output waveform quality.
