-This paper proposes a novel bridgeless single-stage step-up voltage rectifier. Rectification, voltage step-up, and power factor correction functions can all be achieved in a single-stage circuit. The proposed circuit could be used as a power supply for high-voltage battery chargers. The proposed circuit topology is based on a conventional voltage doubler. Two voltage doublers are connected in parallel for reducing the output voltage ripple. Two pairs of thyristors are implemented instead of the original diode for controlling the circuit. The analysis of the circuit operating process is demonstrated, and a prototype is built and tested. The experimental results verify that the proposed rectifier has good boost ratio, output voltage ripple, and power efficiency and an acceptable power factor function.

“…The working status of CCM is shown in Figure 3.In the continuous mode, the instantaneous value of the AC input current is used to track the instantaneous value of the AC voltage of the grid and the current ripple is also small. This not only reduces the design volume of the filter, but also greatly reduces the current peak of the switch tube [3] [4] . The working status of DCM is shown in Figure 4.…”

Abstract. Traditional rectifier circuit by the diode or thyristor, work to produce a large number of harmonics. Active power factor correction (PFC) on this basis to add high-performance full-control power electronic devices, such as MOSFET and IGBT, and control the input current to make it close to the sine wave and the unit power factor. In recent years, with the requirements of the performance of electrical equipment continues to improve, this technology has become a hot spot in the field of power electronics research, and has been widely practical application.For the single-switch and DC-side Boost-type boost circuit, this paper uses the current hysteresis control strategy and PI regulator on the DC side of the fixed voltage control. Analyze the continue current mode (CCM) and the discontinue current mode (DCM). Then the harmonic analysis and switching loss analysis are carried out for the two models.Through the PSCAD simulation, total harmonic distortion (THD) of the current harmonics is low by the discrete Fourier transform (FFT) of the AC current waveforms of the two models. In this paper, we use parallel switch on the buffer circuit to simulate the switching losses, DCM control can be a good way to reduce the opening loss of the switch. IntroductionSingle-phase full-bridge controllable rectifier circuit consists of four half-controlled thyristor, by changing the trigger angle to adjust the rectifier side voltage. The disadvantage is the consumption of a large number of reactive power and produce harmonic interference, and the trigger angle adjustment range is limited, the rectifier side voltage range is too limited [1] . In order to solve the above problems, we can use PWM rectifier circuit, that is, all four thyristors replaced by full-control IGBT devices, but compared to thyristors, IGBT expensive and relatively small capacity, the higher the cost of circuit transformation. With the need to rectify the DC drive to drive a substantial increase in power equipment as well as the international restrictions on the implementation of power harmonics standards. Active power factor correction technology has become a hotspot in the field of power electronics, which can add a small amount of full control device to the sine wave current and the unit power factor on the basis of the original uncontrollable or semi-controlled rectifier circuit.As shown in Fig 1, when the controllable switch V is on, the power supply E is charged to the inductor L while the capacitor C supplies power to the load. As the value of C is large, the output voltage U0 is kept constant. When V is in the off state, E and L collectively charge the capacitor and supply energy to the load R. Boost type has been able to make the output voltage higher than the power supply voltage, the key for two reasons: First, the inductance L after the energy storage has the role of voltage pump, and second, the capacitor C can maintain the output voltage.As shown in Fig 2, in the rectifier circuit DC side by adding Boost module, you can meet the following c...

“…Currently, ac-to-dc conversion systems are widely used to supply power from the ac grid for various applications, such as battery chargers, electronic ballasts, household electric equipment, switch-mode power supplies (SMPS), uninterrupted power supplies (UPSs), and motor drives [1], [2]. However, conventional ac-to-dc converters based on diode or thyristor rectifiers draw pulsed currents from the utility grid.…”

This paper introduces a simple grid-voltage-sensorless control scheme for single-phase power factor correction (PFC) boost converters. The grid voltage waveform is obtained based on the dc output voltage, the switching duty ratio, and a phase-lead compensator. In addition, the duty ratio feedback is utilized to obtain the unity input power factor and the zero harmonic current. The proposed control scheme is designed and mathematically analyzed based on a small-signal model of PFC boost converters. To verify the effectiveness of the proposed control scheme, several simulations and experiments are carried out in two applications: an industrial power system with a 60 Hz grid frequency and a commercial aircraft application with a 400 Hz grid frequency.
