SOFT-START FOR RESONANT CONVERTERS |
摘要 |
A start-up circuit for a resonant converter is arranged such that, during start-up of the resonant converter, the start-up circuit provides a drive signal that is to be applied to a switching transistor of the resonant converter and that has a variable duty cycle and a variable frequency. A converter includes a voltage source, a capacitor connected to the voltage source, a first switching transistor connected to the voltage source, a transformer connected to the capacitor, and a start-up circuit arranged to drive the first switching transistor with the drive signal during start-up of the converter. A start-up method for a resonant converter including a first switching transistor includes driving the first switching transistor with a variable duty cycle and a variable frequency. |
