Abstract
A current mode resonant converter integrates current information from a first drive transistor to generate an integration signal. The integration signal is added to a sawtooth signal to generate a quasi-sawtooth signal. The quasi-sawtooth signal is compared to an error signal indicative of an output voltage of the resonant converter. The first drive transistor is switched OFF when the quasi-sawtooth signal reaches the level of the error signal. Once the first drive transistor is turned off, a second drive transistor is turned on for the same time duration same as the first drive transistor.
