MMC power module overvoltage protection circuit and multi-stage bypass method

This invention discloses an overvoltage protection circuit and multi-stage bypass method for an MMC power module. The circuit includes a bypass switch connected in parallel across the MMC power module. When the capacitor voltage of the MMC power module exceeds a set safety value, the bypass switch closes, bypassing the MMC power module.
