Abstract :
We are reporting on a compact high voltage (HV) power supply that can be used in the mobile or airborne generation of high power microwave generators. The charger uses rectified AC mains input voltages of 480 V three phase and produces output voltages of more than 55 kV with HV output power levels of 100´s of kW continuously. Major advancements over a previous design are the design of the secondary winding of the HV nano-crystalline transformer, the control of the primary inverter and the thermal management and diagnostic of the HV-DC rectifier.
