Choosing a high voltage switch

Choosing a HV switch Due to advances in semiconductor technologies, solid-state switches can now substitute thyratrons, ignitrons, spark gaps and electromechanical high voltage relays. TTL control input and low power electronics replace expensive heater supplies and drivers found in older systems. A high voltage switch... Read more
