Abstract

This paper analyzes the working principle of flying capacitor boost converter and its different variants such as synchronous flying capacitor boost converter and n-level flying capacitor boost converter. The circuit diagram and analysis of different waveforms have been provided. Voltage conversion ratio of different converters have been provided. The lower voltage conversion ratio (VCR), higher voltage stress, and low efficiency of the boost converter at higher duty cycle levels are the primary limitations of the device. Magnetic coupling components are employed to boost the VCR, but the rating is reduced as a result. The leakage current stored in the magnetic component causes unwanted voltage spikes to occur in the switches as a result of the leakage current. For the purpose of addressing these difficulties, several active and passive clamping switches are employed. Three-level boost converters are an excellent alternative to conventional boost converters, but they have a number of disadvantages that must be considered before using them.

Keywords: Flying capacitor boost converter, Voltage conversion ratio, Flying capacitor, Boost converter
