High-potential isolated power supply in semiconductor high-voltage valve application circuit

The invention belongs to the technical field of multi-energy utilization, and particularly relates to a high-potential isolated power supply in a semiconductor high-voltage valve application circuit.The high-potential isolated power supply comprises a high-voltage semiconductor valve group, an AC current source, a high-voltage isolation transformer, a valve section energy-receiving transformer, aunit energy-receiving transmitter and a unit control power supply. A high-voltage isolation transformer LH0 and an AC transformer matching the voltage-to-earth class of one end of the high-voltage semiconductor valve group bear the main insulation. Longitudinal insulation is shared by the multiple valve segment energy-receiving transformers. The high-voltage semiconductor valve group is composedof multiple segments, each segment is provided with a valve segment energy-inducing transformer, and the insulation of each current transformer matches the longitudinal insulation voltage class sharedby the section. The high-po
