POWER CONVERTER AND OPERATING METHOD THEREOF

The invention relates to a power converter and an operation method thereof. One example is a method of operating a power converter, the method including: during a first on time, charging a first output inductor through a first switching tank circuit defining a first switching node coupled to a first lead of a resonant inductor; generating a first current into the first switching tank circuit through the resonant inductor during the first on time; and then during a second on time, charging a second output inductor through a second switching tank circuit defining a second switching node coupled to a second lead of the resonant inductor; and generating a second current into the second switching tank circuit through the resonant inductor during the second on time. 本发明涉及电源转换器及其操作方法。一个示例是一种操作电源转换器的方法，该方法包括：在第一接通时间期间，通过第一切换储能电路对第一输出电感器充电，该第一切换储能电路限定耦接到谐振电感器的第一引线的第一开关节点；在该第一接通时间期间，通过该谐振电感器向该第一切换储能电路中产生第一电流；以及然后在第二接通时间期间，通过第二切换储能电路对第二输出电感器充电，该第二切换储能电路限定耦接到该谐振电感器的第二引线的第二开关节点；以及在该第二接通时间期间，通过该谐振电感器向该第二切换储能电路中产生第二电流。
