Abstract
A sub-microsecond pulsed electric field generator is disclosed. The field generator includes a controller, which generates a power supply control signal and generates a pulse generator control signal, and a power supply, which receives the power supply control signal and generates one or more power voltages based on the received power supply control signal. The field generator also includes a pulse generator which receives the power voltages and the pulse generator control signal, and generates one or more pulses based on the power voltages and based on the pulse generator control signal. The controller receives feedback signals representing a value of a characteristic of or a result of the pulses and generates at least one of the power supply control signal and the pulse generator control signal based on the received feedback signals.
