Abstract: A power supply apparatus includes a power factor correction circuit, an LLC converter, an auxiliary conversion circuit, a secondary side controller and a voltage tracking circuit. The power factor correction circuit is used for converting a DC link voltage into a first voltage. The LLC converter includes a primary side circuit and a secondary side circuit, which are coupled with each other. The primary side circuit receives the first voltage. The first voltage is converted into an auxiliary voltage by the auxiliary conversion circuit. The voltage tracking circuit detects the auxiliary voltage and issues a detection signal to the secondary side controller. The secondary side controller tracks a ripple change of the DC link voltage and instantly generates a reverse waveform opposite to a waveform of the DC link voltage. The secondary side controller controls the operations of the LLC converter according to the reverse waveform.
