Claim 6:
7. A system comprising:
a pulse power drilling assembly to be positioned in a borehole formed in a subsurface formation, the pulse power drill assembly to drill the borehole based on periodic pulses of electrical discharges into the subsurface formation, the pulse power drilling assembly comprising,
a center flow tube to through which a drilling mud is to flow for drilling the borehole;
at least one primary capacitor to store electrical power at a first voltage, wherein, after at least one discharge criteria is satisfied, the at least one primary capacitor is to discharge the electrical power at the first voltage;
a transformer coupled to the at least one primary capacitor and encircling the center flow tube, wherein the transformer comprises,
at least one primary winding;
a core encircling the at least one primary winding, wherein the core comprises an electrically non-conductive material; and
a secondary winding encircling the core, wherein the transformer is to transform the electrical power from the first voltage to a second voltage that is higher than the first voltage; and

at least one electrode to output a pulse of the periodic pulses of the electrical discharges into the subsurface formation based on the electrical power transformed to the second voltage.
