Claim 0:
1. A method comprising:
drilling a borehole into a subsurface formation based on periodic pulses of electrical discharges emitted from a pulse power drilling assembly into the subsurface formation, wherein the drilling comprises,
flowing a drilling mud through a center flow tube of the pulse power drilling assembly;
transforming, using a transformer in the pulse power drilling assembly, power from a first voltage to a second voltage that is higher than the first voltage, wherein the transformer comprises at least one primary winding that encircles the center flow tube, a core that encircles that encircles the at least one primary winding, and at least one secondary winding that encircles the core, wherein the core comprises an electrically non-conductive material; and
transferring the power periodically to electrodes of the pulse power drilling assembly; and
emitting, from the electrodes, the periodic pulses of the electrical discharges into the subsurface formation based on the power.
