The design and performance of the pulsed-power system for the FRX-C compact toroid compression heating experiment are reviewed. Two inductively-isolated, 10-kV capacitor banks (total energy =1.5 MJ) are discharged through a common, low-inductance load. The S-MA currents are switched and crowbarred with parallel arrays of sizeD ignitrons. Power supplies are constructed in simple 25 and 50 kj modules, each capable of supplying 100 kA at 10 kV. Non-negligible source inductance and the addition of highpower resistors maintain module isolation and protect the system during fault modes.
