Double voltage rectification output power supply circuit of boosting transformer

The utility model discloses a double voltage rectification output power supply circuit of a boosting transformer used for providing working power supply for an electrowetting dust remover. The double voltage rectification output power supply circuit comprises a boosting transformer double voltage rectification circuit, which comprises a transformer boosting circuit and a double voltage bridge type rectification circuit. The output end of the boosting transformer double voltage rectification circuit is connected with the electrowetting dust remover, and the input end of the boosting transformer double voltage rectification circuit is connected with commercial power. The double voltage rectification output power supply circuit is advantageous in that when the short circuit or the circuit break of the electrowetting dust remover occurs, the short circuit current and the circuit break voltage can be loaded on the capacitor of the double voltage bridge type rectification circuit, and then the damage of the short circuit current or the open-circuit voltage on other devices can be prevented, and therefore even when the long-term short circuit occurs, the energy loaded on the capacitor is the reactive loss, the circuit is environmental-friendly, energy-saving, and emission-reducing, and the anti-impact function, the short circuit prevention function, and the open-circuit prevention function of the load can be provided.
