Abstract

The embodiment of the present invention relates to a latch current limiter (LCL) circuit for spacecraft and a spacecraft power system using the same. The LCL circuit are coupled between a power supply terminal and a power receiving terminal, wherein a semiconductor switch circuit is configured between the power supply terminal and the power receiving terminal. The semiconductor switch circuit includes a conduction mode, a cut-off mode and a resistance mode. Moreover, an LLC DC-to-DC converter is adopted for controlling the semiconductor switch circuit. When the current is greater than the over-current value, the LLC DC-to-DC converter changes its operational frequency to change the output voltage such that the semiconductor switch circuit is controlled to enter the resistance mode. After a preset period, when the current does not return the regular value, the LLC DC-to-DC converter controls the semiconductor switch circuit to enter the cut-off mode such that the power which supplies to the load is turned off.
