A Three-Phase Multilevel Hybrid Switched-Capacitor PWM PFC Rectifier for High-Voltage-Gain Applications Abstract This paper presents a three-phase multilevel power factor correction rectifier using the hybrid switched-capacitor concept is proposed. The converter is suitable for high-voltage-gain applications from conventional three-phase low-voltage sources. The three-level voltage operation reduces the weight and bulk of the magnetic devices. The main advantages of the proposed converter are low number of active switches, high voltage gain, sinusoidal currents, low voltage stress across all components, and simple control. Both steady-state and dynamic analyses are investigated. Existing method The existing method describes the power flowis unidirectional and the conventional grid is the main source, being the load supplied through a high dc-link voltage. Because of this, a high-voltage ac–dc power conversion is necessary. For low-power levels, single-phase voltage multiplier circuits are often employed due to robustness and simple operation. With the increase of the power load, the use of three-phase converters becomes necessary Proposed method The proposed method describes This converter merges three voltage multiplier cells connected to isolated three-phase voltage source to achieve high gain conversion. It has the advantage that all semiconductors are subjected to low voltage, which allows the operation with high dc-link voltage. As a drawback, the capacitors operate at the grid frequency, leading to an increase of the bulk and weight of the conversion system. Moreover, the ac currents have high harmonic distortion due to absence of active control.
