In this paper, a comparative analysis of Power Factor Improvement (PFI) of three phase boost rectifier is simulated using PSpice software. The proposed model is compared with the conventional model and the results shows that a great improvement is achieved in the power factor by reducing the total harmonic distortion (THD) using active switching an...

A new three-level inverter based on the switched capacitor (SC) with a common grounding (CG) configuration has been introduced in this paper, which is capable of boosting the input voltage up to three times. Therefore, this inverter is configured without any boost dc/dc converter stage for low voltage PV application. To step up the input PV voltage...

... Harmonics create a lot of problems [10]. Combining active and passive filter [11], switch mode regulator [12], Cúk converter in DCVM operation [9] and Cúk converter with variable switching frequency [13][14][15][16] to reduce the THD is proposed. But in every case, it is found that the value of THD is greater than 2%. ...

Rectification is a very common term in power electronics sector, where an AC signal is converted into a DC signal. But this process comes up with few problems, such as, distortion of input current. With high amplitude, the total harmonic distortion (THD) increases. To solve these problems, passive filtering is used to decrease harmonic distortion and to improve the nature of input current. But filtering brings lower output voltage. To solve this problem, output filtering is used with the DC-DC regulator. In this paper, the input side current of a three phase Cúk rectifier is improved with respect to output voltage level, efficiency and optimum total harmonic distortion using passive filters and PWM technique. Simulation results are presented to show the effectiveness of the design.
