An SCR-based regenerative converter for VSI drives

Avoiding Regeneration with a Matrix Converter Drive

“…In this system, the regenerative energy is not put back onto the main bus since the diode bridge is a uni-directional circuit [12,13] …”

“…When using a diode bridge fed VSI, regenerative energy is not put back onto the supply since the diode bridge is a uni-directional circuit [12,13] and hence bi-directional power flow is not possible. The conventional dynamic braking method is used to avoid regeneration in this kind of DC-Link converter as shown in figure 2.2.…”
