1. A method comprising:
receiving, at a power conditioning system positioned within a pulse power drilling assembly, an electrical power output generated by an alternator operating within the pulse power drilling assembly as part of a pulse power drilling operation; and
conditioning, using the power conditioning system, the received electrical power output to generate a conditioned electrical power output to be coupled to a pulse power unit of the pulsed power drilling assembly, wherein conditioning the received electrical power output comprises:
rectifying the electrical power output to generate a rectified power output,
splitting a waveform of the rectified power output into two parallel signals,
transforming a voltage level of each of the two parallel signals to one or more higher voltage levels,
rejoining the two parallel signals at the one or more higher voltage levels, and
outputting a conditioned electrical power output comprising the one or more higher voltage levels to the pulsed power unit.
