摘要： The present invention relates to a power controller with a current limiting function for pre-charging a capacitive load, wherein current limitation is implemented by means of power transfer modulation control under specific switching conditions. Specifically, by use of resonant circuit elements (resonant tank) and an accordingly adapted modulation controller, a zero-voltage switching condition (ZVS) when modulating the power transfer is achieved. This results in low power dissipation and little electromagnetic interference. Therefore, a capacitive load can be charged faster and with less power dissipation than in conventional approaches.

摘要： An inrush current limiter for electronic fuses detects the type of load connected to the electronic fuse at ignition. By detecting the type of load, the limiter prevents a large peak current from flowing through the fuse. When a short circuit occurs, the limiter ensures that the electronic fuse only operates once in linear mode.

摘要： An AC circuit breaker 3 is provided between an AC system 1 and an AC-DC converter 5, and a DC circuit breaker 7 is provided between a DC line 6 and the AC-DC converter 5. A bypass switch capable of short-circuiting a converter cell included in the AC-DC converter 5 is connected to the AC-DC converter 5. At the time of a fault in the DC line 6, the bypass switch is turned on to interrupt the supply of DC power from the AC system 1 to the DC line 6.

In the embodiments of the present invention, a connector can be inserted and disconnected without generating an electric arc, thereby avoiding generating an arc discharge, and implementing arc-free hot plugging of a high voltage direct current power supply apparatus; moreover, no improvement needs to be made to the connector itself, so that the connector has a relatively small size.
