摘要
High voltage is connected and disconnected in less than a microsecond from a high voltage power supply to a radar transmitter using a solid state relay. The solid state relay supplies this high voltage using multiple power MOSFETs, which are serially-connected between the source and the load. The gate of each power MOSFET is simultaneously triggered by trigger circuits which, in turn, are activated and coupled by a single turn transformer. The transformer is driven by a pair of field effect transistors, which are activated by a pair of open collector comparators. The open collector comparators only activate when they receive a signal indicating that the radar transmitter should transmit a waveform.
