Development of An Integrated Circuits for Non-Isolated DC-DC Converters

Non-isolated buck circuit, boost circuit, buck/boost circuit and Cuk circuit are important basic circuits of DC-DC converters. An integrated circuit of these four circuits has been developed and presented in this paper. The integrated circuit was developed according to the rules of thumb. It can be applied to energy storage systems, uninterruptible power systems and charging systems to improve the application flexibility of these systems.
