Abstract
Provided in an embodiment is a control method in use of an LLC converter with high-side and low-side switches connected in series between two input power lines via a first node. Connected to the first node is a resonant circuit with a primary winding of a transformer and a resonant capacitor both connected to a second node, to which a voltage divider is connected to generate a feedback signal at a feedback node. First and second control signals are generated to control the high-side and low-side switches respectively in response to the feedback signal and a compensation signal controlled by an output voltage of the LLC converter. A first duty cycle of the first control signal is compared with a second duty cycle of the second control signal to provide an accumulation signal, in response to which an adjustment current is provided to adjust an average of the feedback signal.
