Abstract

The invention relates to a d.c.-a.c. converter with an asymmetric half-bridge circuit (1) that has an energy-storing component (6). The controllable switching means (2, 5) of the asymmetric half-bridge circuit (1) are driven by means of phase-shifted control pulses, the control pulses partly overlapping in time. The pulse width of the phase-shifted control pulses is substantially 180 electrical degrees.
