Abstract
In this chapter, ZCS control techniques for inductor-based boost converters are presented. The ZCS circuit controls the high side switch of the synchronous inductor converter to maintain the output voltage and hence the efficiency. In the first section, several reported ZCS techniques are explained and compared in regard to design, complexity, and efficiency. Then, an example of an efficient ZCS method is introduced which is designed to enhance the dynamics of the inductor converter as well as the efficiency. Measurement results are presented which confirm the operation of the ZCS circuit.
