Inverter with current rise limiter has capacitive dc circuit with two current limiting networks and bi-directional power semiconductor switches in parallel with loss limiting circuit

摘要

Inverter with current rise limiter comprises a two series capacitance dc circuit (1) with two current-limiting networks (5,10) and four bidirectional controllable power semiconductor switches (S1-4) and two unidirectional switches (S5,6). A parallel resistance (15) and capacitance (16) circuit limits switch-off loss.
