摘要: A power conversion device includes a full-bridge switch circuit, a converter circuit, and a control circuit. The full-bridge switch circuit is operable to convert a direct current input voltage to a converted voltage. The converter circuit converts the converted voltage into a direct current output voltage. The converter circuit includes a resonant inductor, a transformer, a first converter switch, a second converter switch, an output inductor, and an output capacitor. The direct current output voltage is provided across the output capacitor. The control circuit controls the full-bridge switch circuit, the first converter switch and the second converter switch based on the direct current output voltage and a reference voltage.

摘要: A voltage stabilizing circuit includes an input capacitor, a booster circuit having an input side coupled across the input capacitor, a first output capacitor coupled to an output side of the booster circuit, and a series connection of a first power switch and a second output capacitor coupled between two terminals of the first output capacitor. The first power switch has a terminal coupled to one terminal of the first output capacitor. The second output capacitor has a first terminal coupled to the other terminal of the first power switch at a common node, and a second terminal coupled to the other terminal of the first output capacitor. A second power switch is coupled between the input capacitor and the common node.
