Abstract
A control circuit for a DC-AC converter which improves the efficiency of the converter and enables it to operate at a higher frequency using the same semiconductor switches. The residual voltage across the conductive switch (9, 10) of the converter is compared with a reference voltage (23) via an analog OR-gate (26) and the control signal for the conductive switch is controlled such that the residual voltage is set to a desired value.
