Patent ID: 7843087

Claim:
A pulse power generator comprising: a plurality of power stages connected in series with one another, each power stage including a plurality of power cells connected in series with one another, wherein each power cell has a semiconductor switch and a charge capacitor, an emitter of the semiconductor switch being connected to the charge capacitor, a power switch driver for driving the semiconductor switch, a bypass diode connected to both ends of the semiconductor switch, and a rectifying diode connected to both ends of the charge capacitor and the semiconductor switches of the plurality of power cells are connected in series with one another; a power inverter for supplying power so as to charge the charge capacitor; a power loop for allowing a power to be supplied to the rectifying diodes within the respective power cells of each power stage from the power inverter, the power loop being formed of a high-voltage insulating cable; a control inverter for supplying a control signal so as to generate a gate signal and a gate power of the semiconductor switch; and a control loop for allowing the control signal to be supplied to the power switch drivers within the respective power cells of each power stage from the control inverter, the control loop being formed of a high-voltage insulating cable, whereby the plurality of power stages are connected in series with one another so that the entire semiconductor switches are connected in series with one another.
