Abstract
An objective of the disclosure is to provide a power supply cell of a power supply system and a power supply system using the same. The power supply cell includes a first power conversion circuit operative to output a first DC voltage across its first positive terminal and first negative terminal, a second power conversion circuit operative to output a second DC voltage across its second positive terminal and second negative terminal, a first controllable unidirectional semiconductor switch operative to generate a first conduction path from the first positive terminal of the first power conversion circuit to the second negative terminal of the second power conversion circuit, a first unidirectional semiconductor switch operative to generate a second conduction path from the first positive terminal of the first power conversion circuit to the second positive terminal of the second power conversion circuit, a second unidirectional semiconductor switch operative to generate a third conduction path from the first negative terminal of the first power conversion circuit to the second negative terminal of the second power conversion circuit, a first low-pass filter, a second low-pass filt…
