“…The passive filter introduces bulky inductors and capacitors, which are costly and less flexible. Alternatively, the active filtering technique incorporates high frequency switching arrangements, for which the size of filter capacitor and inductor has been reduced [10][11][12][13][14][15]. Consequently, active filtering technique has achieved its acceptancy among researchers as well as industrial engineers.…”

DC power supply has become the driving source for some essential modern applications. Thereby, DC power conditioning has become a significant issue for engineers. Typically used rectifiers associated with a bridge structure is nonlinear in nature. Thereby, the current at input side of the rectifier contains harmonics, which also flow through the power line. The presence of harmonics causes several interruptions and reduce power quality. In this regard, a new close loop SEPIC controlled rectifier is proposed in this paper. The conventional scheme is arranged with a rectifier connected to a DC-DC converter, which is an open loop system. Consequently, such system cannot regulate voltage at load varying condition. The proposed SEPIC controlled rectifier can regulate voltage under load varying condition for a wide range. Additionally, the performance in terms of total harmonic distortion (THD) of input current and power factor at AC side are also within satisfactory range for the closed loop configuration. The controlled rectifier has four operating phases associated with switching states and input voltage polarity. The close loop configuration also incorporates a current and a voltage loop at the feedback path. The comparative studies have been performed among the proposed closed loop construction, the open-loop structure as well as the conventional construction. The effectiveness of the proposed controlled rectifier is verified in terms of THD and input power factor considering the results obtained from simulation.

“…Thus, researchers have proposed a new PFC technique which comply the setup standard such as IEC555-2 and IEC6100-4-7. In addition, the galvanic isolation is also one of the state requirements in international electrotechnical commission (IEC) standard [4] for the safety of the end user. However, the total cost is also one of the key factors to meet the setup requirements.…”

A small-signal analysis of a single-stage bridgeless boost half-bridge alternating current/direct current (AC/DC) Converter with bidirectional switches is performed using circuit averaging method. The comprehensive approach to develop the small signal model from the steady state analysis is discussed. The small-signal model is then simulated with MATLAB Simulink. The small-signal model is verified through the comparison of the bode-plot obtained from MATLAB Simulink and the simulated large signal model in piecewise linear electrical circuit simulation (PLECS). The mathematical model obtain from the small-signal analysis is then used to determine the proportional gain K_p and integral gain K_i. In addition, the switch large-signal model is developed by considering the current and voltage waveforms during load transients and steady-state conditions.

“…Passive and active filtering are two commonly used methods to remove harmonics. The Passive filter needs bulky indictors and capacitors which is costly and imposes a restriction on the mobility of the converter [7,[9][10][11][12][13]. The active filter usually consists of a switch of high frequency and reduced sized inductors and capacitors.…”

“…These types of conventional circuits are consists of a rectifier cascaded with a DC-DC converter. Newer circuits have also been designed using the single switch at the input side of power converters [5,7,10,11,[14][15][16]. These converters give improved performances in terms of Total Harmonic Distortion (THD) and power factor at AC side.…”

<span lang="EN-US">A new closed loop AC to DC ĈUK converter is presented in this paper. The conventional ĈUK AC to DC converter has no feedback circuit. Thereby, the output voltage of the converter changes while changing the load. The proposed closed loop converter can regulate voltage with the variation of load over a wide range. Moreover, the power factor and Total Harmonic Distortion (THD) of the supply side current found quite satisfactory from this closed loop ĈUK converter. The converter operates in four steps with a different combination of voltage polarities and switching states. The feedback path consists of a voltage control loop and a current control loop. The closed loop ĈUK converter in this study is compared with the open loop version. Additionally, the comparison is made with the conventional converter of the same topology. The effectiveness in terms of power factor and THD of the proposed converter is verified using simulation results.</span>
