摘要： A converter bridge arm suitable for high-voltage applications and an application system thereof. The converter bridge arm comprises an energy storage capacitor (C) and a plurality of reverse-conducting switches, and is formed by serial connection of an upper telescopic arm (Bu), a lower telescopic arm (Bd) and an inductor (Lb). The upper telescopic arm (Bu) and the lower telescopic arm (Bd) are respectively formed by cascading connection of a plurality of units. The converter bridge arm has a simple modular structure, is easy to control, reliable and convenient for starting a high-voltage circuit, has self-balancing voltage sharing effect, and can operate without a transformer and has the characteristic of power bidirectional flow, does not require high-voltage isolation auxiliary power supply, has the advantages of suitability for high-frequency operation and electromagnetic compatibility, and can remarkably reduce the dimension of a filter.
