Abstract
The advantages of DC systems are being revisited in recent times.
The new-age consumer equipments, for example, computers, LED lights, home appliances like LED TV, washing machine, etc., use DC supply for their operation. However, the conventional utility supply is AC.
This paper presents a dual output AC-DC converter as a suitable candidate in emerging DC distribution systems. In accordance with the need of vast range of DC loads and standard distribution levels, the proposed dual output PFC rectifier has been designed to provide simultaneous boost and buck outputs. In addition, the design ensures that the rectifier operates at high power factor.
Therefore, a suitable digital control technique has been implemented for close loop control, which regulates two DC outputs at the same time.
The topology, operating principles, and theoretical analysis of the proposed converter are presented. By using PSIM software, the validation of the converter has been verified.
