A pulse-width modulated circuit applies a voltage (+V) across a load (32) in accordance with a command signal (I). The command signal is con­verted into first and second trains of pulses (x, x′), by electronically comparing the command signal, and its inverse, with a triangular dither signal (38). These two pulse trains (x, x′), and two more pulse trains ( y , y′) obtained by taking the complements of the original pulse trains, are applied to a pair of bridge circuits (48, 50). The load is connected to both bridge circuits. Both bridge circuits include electronic switch­ing devices (60, 62, 64, 66, 68, 70, 72, 74) actuated by the pulses. The bridge circuits are configured such that when a pulse is present, from either the first or the second pulse train, no net voltage appears across the load. At all other times, substantially the entire power supply voltage is applied across the load. Compared to pulse-width modulated circuits of the prior art, having similar pulse frequencies and power supplies, the present circuit reduces the undesirable effects of current ripple through the load by a factor of four. This reduction is due to the use of two alternating pulse trains, which doubles the effective fre­quency of pulses, and to the fact that the maximum voltage excursion of the signal across the load is no greater than the absolute value of the maximum power supply voltage available. As a result, the present circuit has a much higher bandwidth than circuits of the prior art having compa­rable voltage and frequency parameters.
