Resonant switched power converter |
摘要 |
Resonant switched power converter in which the end of a resonant period coincides with the start of a conducting period of a first switching element, undesirable dead times being avoided during the operation of a self-excited synchronous rectifier. To achieve this, a first capacitor is added which has the characteristic that its capacitance is a function of the duty cycle of the first switching element. The variation in the value of the capacitance of the first capacitor is implemented by adding in parallel thereto a serial combination of a second capacitor and a second switching element. The value of the capacitance varies between a first value and a second value.
