ESP Range electrostatic precipitator PSU

The ESP Range has been designed for the Electrostatic Precipitator market.It is a high voltage power supply with an operating frequency of around 25kHz. The example shown is 32kW 80kV and it utilises an IGBT full bridge circuit to convert the DC bus to a high frequency AC waveform. Near full load, the working frequency is close to resonant frequency and almost all of the energy in the resonant components will be delivered to the load.
