Switch mode electrical power controller.

摘要

A switch mode electrical power controller for providing a width modulated output pulse signal in response to a control input signal representing a parameter controlled by the power controller, in which a network for generating the width modulated waveform is capable of combining a ramp waveform signal, a control signal and at least one other signal in generating the width modulated waveform, and a circuit arrangement effects regenerative switching of the network during changes between a first and a second level of the pulse width modulated waveform. <IMAGE>
