A 20 kW inverter flyback charging system has been developed and produced for the ARSR-3 air route surveillance radar system. This precision regulated charging system is used in the transmitter to charge the PFN in a 14- megawatt peak power modulator to over 3,000 volts. The technique used completely eliminates the need for the con ventional regulated, high voltage power supply and the dissipative...
To minimize the switching loss of high frequency thyristors, three kinds of multifinger gates and emitter designs are studied. The device characteristics were evaluated. The power loss during high frequency operation was measured. The rate of rise of forward current was studied.
