Abstract
The present application discloses a pulse voltage generation device, method and controller, the device comprises: a transformer; a first AC/DC conversion circuit, with an alternating current side connected with a high-voltage side of the transformer; an energy storage capacitor, connected with a direct current side of the a first AC/DC conversion circuit, for storing electrical energy; and a discharge control circuit, in parallel connection with both ends of the energy storage capacitor, for controlling discharge of the energy storage capacitor to generate a high-voltage pulse. In the present application, an energy storage capacitor is arranged on a high-voltage side of the transformer, and a discharge control circuit is used to control the energy storage capacitor to discharge to generate a high-voltage pulse, avoiding the problem that frequency of the high-voltage pulse outputted on the high-voltage side is limited by variations of the induced magnetic field of the transformer, and is thus difficult to increase, and that the rising edge and falling edge of the high-voltage pulse take a long time.
