  • Half/full bridge converter
    Patent number: 5859771
    Abstract: Known converters for converting a d.c. voltage at their input to a rectifiable a.c. voltage at the output operate reliably with very small input voltage fluctuations and relatively small fluctuations in load. In order to increase the range of input voltages and loads, it is proposed that a full-bridge converter with filter capacitors in one bridge branch be operated under low-load conditions as a half bridge, such that the capacitors form the midpoint of the half bridge, and under high-load conditions to change to full-bridge operation.
