Rapid Charger for capacitors

The Eagle Harbor Technologies (EHT) Rapid Capacitor Charger was designed for a specific customer application to charge quickly up to 4 nF capacitors in 100 – 300 ns (depending on capacitance). The pulser was tolerant to shorts for up to 3 seconds. Rapid Capacitor Charger is a modified nanosecond pulser of 5 kW.
