An integrated high-power-factor converter with ZVS transition

Category : Power Electronics


Sub Category : AC TO DC CONVERTERS (RECTIFIERS)


Project Code : ITPW01


Project Abstract

This paper proposes a single-phase high-power factor ac/dc converter with soft-switching characteristic. The circuit topology is derived by integrating a boost converter and a buck converter. The boost converter performs the function of power-factor correction (PFC) to obtain high power factor and low current harmonics at the input line. The buck converter further regulates the dc-link voltage to provide a stable dc output voltage. Without using any active-clamp circuit or snubber circuit, the active switches of the proposed converter can achieve zero-voltage switching-on (ZVS) transition together with high power factor that satisfies the IEC 61000-3- 2 standards over a wide load range from 30% to 100% rated power. The steady-state analysis is developed and a design example is provided. A prototype circuit of 60 W was built and tested. Experimental results verify the feasibility of the proposed circuit with satisfactory performance.

EXSISTING SYSTEM

In existing system, PFC rectifiers have been introduced to improve the rectifier power density and reduce noise emissions via soft switching techniques. However, all of these rectifiers operate in DICM and suffers from high switch current stress causing higher conduction losses. PFC rectifiers allow the current to flow through two bridge diodes in addition to the switching component of the converter. This results in higher conduction losses increasing the thermal stresses of the converter. Due to efficiency of the system should reduce.

 

PROPOSED SYSTEM

It performs both CCM, DCM mode the two switches can be driven by the same control signal, which significantly simplifies the control circuit. It can maintain good power factor. Loss also reduced.  These soft-switching techniques have substantially eliminated the switching loss
