Abstract
A controller is adapted for controlling a switch of a resonant direct current/direct current converter, and includes: a pulse width modulation controlling unit for detecting an output voltage of the resonant direct current/direct current converter, and for generating a pulse width modulation signal according to the output voltage detected thereby; a fixed frequency signal generating unit for generating a fixed frequency signal; and a logic synthesizing unit for synthesizing the pulse width modulation signal and the fixed frequency signal so as to generate a driving signal that is adapted to drive the switch of the resonant direct current/direct current converter.
