Abstract
The present invention provides a high voltage regulated DC power supply with full range 24 pulse input for ripple free output for high power RF amplifier, comprising: full range 24 pulse 3 phase 11 kV input system configured to provide uncontrolled low voltage DC bus, low input harmonics and high input power factor; a plurality of DC-DC power modules having their output connected in a series and coupled to the said DC bus voltage; each power module comprising a DC source, an inverter bridge IGBTs operating at predefined duty cycle and staggered to reduce the output ripple and output stored energy; and a combination of feed forward and feedback control circuit adapted to regulate the variations in the input line voltage and the variation in output at various load current to finally obtain ripple free high voltage output.
