Considering the questions of rectifier bridge dual power dissipation fever caused by DC side discharge energy consumption in power supply base on TA principles, and the shortcomings of fluctuating secondary voltage caused by AC side semi-controlled thyristor discharge, design an AC-PWM active bleeder circuit, by regulate the excitation current of high voltage network side power base on gapped core TA principles, So make the operating point in the linear region of the magnetization curve, same time with multiple transient voltage suppression and super capacitor energy storage, and can provide secure instantaneous high power energy output work at low consumption state for long-term for network side monitoring device.
