ABSTRACT:
A switching regulator for regulating an input voltage having an alternating current component. Closure of the regulator switch is determined by a phase shifted switching signal obtained from a control network. In normal operation a varying bias signal coupled to the control circuit varies the phase shift of the switching signal to vary the instant of regulator switch closure. During startup, a capacitance coupled to the control circuit and to the input voltage provides an additional bias signal to delay the switching signal to prevent regulator switch closure during the peak magnitude of the alternating current input voltage component to thereby limit the peak inrush current in the regulator circuit.
