摘要：

The energy supply system of high potential drive circuit is the key device to ensure the stable operation of hybrid DC circuit breaker. Different from the current "magnetic isolation" energy supply principle, based on the capacitance characteristics of DC isolation and AC passed and the series resonant principle of LC circuit, a symmetrical capacitive resonant high-voltage DC device energy supply system is proposed to realize the highly efficient energy supply from ground-potential side to high-potential DC side. The working principle of the proposed energy supply system is analyzed, and the parameter design principle and method based on the proposed topology structure are proposed, together with a certain number of derived topologies. The simulative results show that the energy supply system can still work stably under DC fault, which verifies the feasibility and reliability of the proposed novel energy supply system. © 2021, Electric Power Automation Equipment Press.
