RC 부하에 대한 단방향 구형파 전압 운전에 관한 연구

Common R or R-L load do not need special inverter circuits, however R-C load needs the inverter with circuit that can discharge the capacitor energy. Especially for uni-directional square-wave voltage driving, it becomes more serious problem. In this paper, a energy recovery circuit for uni-directional square-wave voltage driving for R-C load is proposed. With the circuit, the peak load current and the power supply capacity can be reduced because the energy in the load capacitor is saved to a capacitor and re-discharged from the capacitor. The appropriateness is proved from the simulation of the proposed circuit.
