Abstract:
1. A method for delivering a controlled voltage, the method comprising: during a first electric pulse of a plurality of electric pulses delivered to a primary transformer, holding a first switching section open to isolate the controlled voltage, wherein the first electric pulse creates a first magnetic flux in a core of the primary transformer, and wherein the first magnetic flux generates a direct current (DC) magnetizing current; receiving the controlled voltage from a voltage source using the DC magnetizing current at the first switching section; upon termination of the first electric pulse, closing the first switching section to deliver the controlled voltage to the primary transformer; opening the first switching section to stop delivery of the controlled voltage to the primary transformer prior to a start of a second electric pulse of the plurality of electric pulses being delivered to the primary transformer and generating a second magnetic flux in the core of the primary transformer; and closing the first switching section to deliver the controlled voltage to the primary transformer when the second electric pulse terminates, wherein closing the first switching section to deliver the controlled voltage to the primary transformer comprises:
