Abstract

A step-up DC voltage converters circuit and method of operation which overcomes the problems associated with the prior art skip mode converters by reversing the flow of energy in the step-up DC voltage converter at the end of each switching cycle for a short constant time duration, thus making it possible to operate the step-up DC voltage converter over the full load current range at a fixed frequency which substantially facilitates filtering the output voltage. In addition to this the peak-to-peak output voltage ripple is less as compared to that of skip mode converters.
