Abstract :
The energy dissipated in a snubber circuit is proposed as a power supply for the control electronics and auxiliary equipment in a 5 kVA inverter. The power supply circuit is initially supplied by the main DC supply but automatically changes to the snubber circuit as source when the snubber capacitor voltage exceeds a threshold voltage. This increases the total efficiency and reliability of the power supply system, and its effect on the operation of the high-power converter is illustrated.<>
