Abstract


Nowadays the size of the use of electronic devices like laptops, cell phone chargers, electric vehicles and UPS is rapidly increasing. So AC–DC converters need to incorporate the power factor correction along with voltage regulation. There are many AC–DC converter control methods available, but these methods do not perform well. Therefore In this paper, a smooth transformation on switching will be characterized by a high power factor in a single phase AC–DC converter by the use of intrinsic power management strategy. The proposed AC–DC converter's circuit topology is obtained by integrating a boost and buck converter. The Boost Converter's switching frequency does power factor correction to get less current harmonics at the input line. In this single phase AC–DC converter, the buck-boost converter is an important component that increases system power quality based on advanced PWM technique. So in this work, the Intrinsic Power Management Strategy (IPMS) is proposed to enhance the control over the DC–DC converter performance during unstable or transient operation. Rather than making a quick Pulse Width Modulation (PWM) signal, the computerized signal processor just creates a moderate changing DC signal to decide the PWM ramp function. The power factor correction model has been created and simulated by utilizing MATLAB programming. The simulation model demonstrates that the power factor is improved and the converter has regulated DC output voltage. To validate this simulation, a 1000 W prototype converter has been developed to feed a DC motor and the analysis of the results are presented.


Introduction


Nowadays single phase AC–DC converters are broadly utilized in power supplies, battery chargers for home apparatuses and Uninterrupted Power Supplies (UPS). Specifically, the power utilization of data innovation equipment has expanded quickly [1,2] Therefore, AC–DC converters are preferable to achieve high efficiency and low converter cost. The single phase AC–DC converter has been developed with a Power Factor Correction (PFC) and DC–DC Converter. The AC–DC front-end converter in the first stage is required in order to provide low-input-current harmonics so as to meet various standards. Therefore, a number of PFC converters and control methods have been investigated [3]. The simplest configuration of the ac–dc converter with a PFC function consists of a diode rectifier and a chopper circuit [4]. The basic block diagram of the AC–DC converter is shown in Fig. 1. However, the volume of the single-phase buck AC–DC converter becomes larger because the large inductor is required in order to decouple the power pulsation, which is subjected to the power supply frequency. Typically, boost-chopper type single-phase AC–DC converters require a large smoothing capacitor, such as electrolytic capacitors. Large electrolytic capacitors typically have a limited lifetime and increase the volume of the converter [5]. In contrast, for the same reason, buck chopper-type single-phase AC–DC converters require a large smoothing inductor at the dc link part. Since the energy storage density of an inductor is smaller than that of a capacitor, single phase buck AC–DC converters are larger than single-phase boost AC–DC converters. The basic concept is to use an active circuit to absorb the power pulsation from the dc link to other energy storage components, which permits a larger fluctuation of the voltage or current. Therefore, the value of energy storage components can be reduced. So as to conquer this disadvantage, this work presents another single-phase buck type AC–DC converter with a power pulsation decoupling capacity. The proposed converter is developed dependent on a buck-boost type AC–DC topology for PFC utilizing a functioning buffer, which is made out of a single MOSFET switch.
