    • An inverter having a large-capacity self-arc-extinguishing semiconductor element. Recovery capacitors recover energy stored in groups of elements for suppressing the rate of change in current, and are provided within a two-level or three-level inverter bridge. The thus-recovered energy is fed back to a d.c. voltage circuit by an energy regenerative circuit. The energy regenerative circuit controls the charging voltage of the recovery capacitors in proportion to the magnitude of a load current. In a case where the inverter includes inverter bridges connected to a single d.c. voltage circuit, the inverter bridges are divided into groups. A different energy regenerative circuit is connected to the inverter bridge on a per-group basis, and each of the energy regenerative circuits feeds power back to the d.c. voltage circuit.
    • 具有大容量自熄灭半导体元件的逆变器。 恢复电容器恢复存储在元件组中的能量,用于抑制电流变化率,并且设置在二电平或三电平逆变桥内。 这样回收的能量被反馈到直流电。 电压电路由能量再生电路。 能量再生电路根据负载电流的大小控制回收电容器的充电电压。 在逆变器包括连接到单个直流电的逆变器桥的情况下。 电压电路,逆变桥分为组。 不同的能量再生电路以每组的形式连接到逆变桥,并且每个能量再生电路将功率馈送回直流。 电压电路。
