A high-voltage optically controlled bidirectional switch group

ActiveCN224289775UGuaranteed simultaneityImprove insulation performanceElectronic switchingElectric pulse generator circuitsPulse beamHemt circuits
This utility model relates to the field of high-voltage power supply semiconductor switch technology, specifically a high-voltage optically controlled bidirectional switch assembly. A pair of optically controlled switch valve bodies and voltage equalizing resistor circuits are symmetrically arranged on each partition between the upper and lower plates of the switch assembly. Optical fibers are connected to the optically controlled switch valve bodies, and these fibers are connected to a positive optical pulse generator and a negative optical pulse generator. This utility model uses a high-energy laser pulse beam to trigger the switch's activation, resulting in superior high- and low-voltage insulation and isolation, and eliminating electromagnetic interference. By improving the length of the optical fiber and the trigger pulse timing, the activation time of the multi-stage series semiconductor switches is controlled within 1μs, thus meeting the requirements for multi-stage series applications. Furthermore, the switch assembly adopts a bidirectional design, allowing bidirectional withstand of rated voltage. The contactless design of the switch valves ensures noiseless operation during activation, meeting partial discharge test requirements while being safer, more stable, flexible, and efficient.
