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.

摘要： A power supply apparatus (10) includes a voltage input side (102), a power switch circuit (104), a voltage output side (106), a pulse width modulation signal generating circuit (108) and a burst frequency detection circuit (110). According to a pulse width modulation signal (114), the pulse width modulation signal generating circuit (108) controls the power switch circuit (104), so that the power supply apparatus (10) enters a burst mode. The burst frequency detection circuit (110) detects a burst frequency of the power switch circuit (104). The burst frequency detection circuit (110) informs the pulse width modulation signal generating circuit (108) that the burst frequency is in an audio frequency range if the burst frequency is in the audio frequency range. The power supply apparatus (10) leaves from the burst mode to avoid audio noise.
