Abstract
A switching regulator and method of regulating an ac input signal to provide an ac output signal, receiving the ac input signal, generating a reference signal, detecting the points when the ac input signal is zero and synchronising the reference signal to these points, performing a subtraction between the reference and ac input signals to obtain an error signal, dividing the error signal by the reference signal to obtain a fractional error, and producing a regulated ac output signal by modulating the ac input signal to correct for the fractional error. The switching regulator uses a modulating transistor and clamping diode for each half-cycle of the input signal.
