Abstract
A free-running switching regulator of the type including a transistor switch serially-connected between a voltage source and a load is disclosed. The duty cycle of the switch is varied in response to changes in the load voltage to maintain it at a predetermined regulated magnitude. Feedback means is provided for controlling the switching frequency and the duty cycle of the switch substantially independently of the load impedance such that feedback loop stability is maintained irrespective of the load reactance and an essentially constant switching period of duration T is maintained despite changes in the load resistance.
