ABSTRACT:
A constant frequency switching-type power supply with pulse width modulation control in which the error signal is compared with an auxiliary ramp that starts with the clock pulses as well as with a current ramp signal and in which the clock pulses controlling the closing of the switches are delayed so as to avoid transfer of energy at no load that results from the inherent delay between the time when the current ramp crosses above the error signal and the time when the switches are opened.
