摘 要：
PURPOSE:To obtain a power converter in which the compositional elements of inverter can be protected against breakdown due to open-phase when divided DC voltages are inverted through an inverter into AC voltages which are then combined through a transformer. CONSTITUTION:AC component
detecting means 4A, 4B, 4C detect AC components of input voltages to inverters 5A, 5B, 5C, 5D. Open-phase detecting means 8A, 8B, 8V detect open-phase of output voltages from the inverters based on the AC components thus detected. A protective circuit 9 produces a signal for stopping operation of all inverters when open-phase is detected by at least one open-phase detecting means. 主权项：
