Solid state modulator based on multi-primary winding pulse transformer

A solid state modulator with peak output power up to several MW is introduced in this paper. This kind modulator is characterized by repetitive frequency and easily-adjustable width of the output pulse for utilization in solid state switch. Storage capacitors of the modulator are charged by HF-inverter charging power supply in constant current mode. A step-up multi-primary winding transformer is applied to decreasing each exciting unit’s operation voltage and current, which could avoid circuit complexities caused by solid state devices connecting in series or parallel. RL pulse compensating network is introduced to counteract top-droop caused by pulse transformer or low capacitance of storage capacitors. With above methods, A magnetron modulator with a peak output voltage of 48 kV, a puls
