摘要： The present disclosure relates to a power conversion system. A first boosting circuit of the power conversion system is coupled between a first energy storage element and a second energy storage element. A switching element of the power conversion system is coupled to the first boost circuit in parallel. When the first voltage value is lower than a first preset level, the control circuit turns off the switching element and drives the first booster circuit to maintain a second voltage value according to the first voltage value, so that the power conversion system operates in a first state. When the first voltage value is equal to or larger than the first preset level, the control circuit turns on the switching element and turns off the first boost circuit, so that the power conversion system operates in a second state.
