In a 3-phase third harmonic auxiliary impulse commutated electric power inverter the d-c terminals of which are connected, via a circuit having appreciable electrical inductance, to a voltage source comprising a battery, the commutation capacitor is precharged by cyclically manipulting the conducting periods of selected main and auxiliary valves of the inverter so that a series of discrete pulses of capacitor charging current flow from the battery through a path comprising the aforesaid circuit, part of the inverter load circuit, and the capacitor, with alternate pulses of current traversing the capacitor in one direction and intermediate pulses traversing it in the opposite direction. Such action continues for a sufficient number of cycles to "ring up" the capacitor to a voltage magnitude more than five times higher than the battery voltage.
