Performance evaluation of single-phase AC-DC converter using versatile power balanced control method [articol]

Abstract

The enormous application of converters in the electrical system, the power quality at input mains affected extremely. So, to enhance the system power quality, innovative techniques can be used. This paper contains advanced AC to DC converter technique that not only provides better DC output but also stabilizes the input AC power source. It also provides advantages like lower production costs and reduced component count. In this AC to DC conversion system, the combined circuit of both bridge rectifier and buck-boost converter are used for the proposed model, and it also provides stable output power for a load demand up to 1000 Watts. In this system, continues and discontinues modes of operation will be performed for buck-boost converters. The additional advantages of this system are transformerless AC to DC conversion provides high efficiency with less power absorbing capability. This paper proposes a Versatile Power Balanced Control (VPBC) based controller derived for the Buck-Boost converters in the single-phase single stage AC to smaller weight, size, reduced components, and better output voltage regulation. This paper also concentrates on the input source power factor stabilization. The circuit components are well designed according to different operating conditions with various loads and different source voltage.
