Abstract
Systems and Methods for providing power to downhole to a pulsed drilling scheme. For example, methods and systems herein may comprise a pulsed power drill bit comprising one or more electrodes, and a pulse-generating (PG) circuit configured to provide an electric potential across the one or more electrodes. In addition. a boost charger configured to charge an energy storage component in the PG circuit and a power supply configured to provide voltage to the PG circuit.
