Abstract: With the goal of producing a soft switching boost converter having a simple structure, high efficiency, high frequency, low voltage stress, and ease of control, a new zero-current soft-switching pulse frequency modulation (PFM) converter was described herein. The operation principle of this converter is explained using the boost converter as an example. The soft switching and other design aspects are also outlined in detail. Simulation and experimental results show that the converter can produce a steady zero current swith under a relatively broad range of changes in output and input voltage, load, and control frequency. This new soft switching cell can also be used in other basic DC-DC converters.
