Abstract: A resonant converter switching between different operational state modes is provided. The resonant converter includes a first transistor, a second transistor, a control circuit, a resonant circuit, a transformer and an output stage circuit. A first terminal of the first transistor and a second terminal of the second transistor are connected to positive and negative terminals of an input voltage source, respectively. A first terminal of the second transistor is connected to a second terminal of the first transistor. The resonant circuit is connected to the second terminal of the first transistor and the transformer. The transformer is connected to a load through the output stage circuit. The control circuit modulates frequencies or duty cycles of conduction time control signals that are outputted to the first and second transistors to different values for switching the resonant converter between the operational state modes.

Abstract: A resonant converter having a switch on-time control mechanism is provided. The resonant converter includes a primary-side switch circuit, a primary-side resonant circuit, a secondary-side switch circuit, a secondary-side resonant circuit, a transformer and a control circuit. In the resonant converter, the control circuit controls on-times and switching frequencies of the primary-side switch circuit and the secondary-side switch circuit to extend time within which power is transmitted from an input power source, the primary-side switch circuit, the primary-side resonant circuit and the transformer to the secondary-side resonant circuit, and stored in the secondary-side resonant circuit. As a result, the secondary-side resonant circuit is able to supply more power to a load.
