Switching energy feedback device for bridge circuit

摘要

The energy feedback device uses a transformer (1) across a diagonal of the bridge circuit, a booster coil (2) between a pulsed DC voltage input (3) and the switching elements (S1,S3) in one half of the bridge and an energy storage capacitor (5) and a current source (16) for feedback of the energy stored in the capacitor. The stored energy is fed back directly via the transformer.
