Negative High Voltage Power Supply (HVPS) For Laser Beam Printer Applications

摘要

A novel negative high voltage power supply that features the high input to output step-up voltage conversion ratio characteristics is presented. The proposed circuit features the reduced voltage stresses of the components compared to those of the conventional ones. The operational principles of the proposed circuit are analysed and comparative features are presented. The simulation results and experimental results are presented to verify the validity of the proposed circuit.
