Abstract
A multi-loop controller component for an electric discharge machining (EDM) system includes a plurality of power loop circuits coupled to an output of a power supply of the EDM system and configured to receive DC electric power from the power supply. Each power loop circuits electrically-isolated from other power loop circuits. The multi-loop controller component also includes a plurality of transistors. Each transistor is coupled to a respective power loop circuit and is configured to switch between an ON state and an OFF state to generate a pulse of the DC electric power through the respective power loop circuit. In addition, the multi-loop controller component has a drive controller coupled to the plurality of transistors. The drive controller is configured to transmit at least one control signal to at least one of the transistors to facilitate switching the transistor between the ON state and the OFF state.
