“…In contrast, some complex designs and control methods were presented in [6], which recently introduced a literature review for the boost converter topology, such as the traditional bridge boost converter with PFC, PFC with pseudo-continuous conduction, interleaved PFC, hybrid interleaved PFC, and PFC with a bidirectional switch. However, detailed the emerging disadvantages of such topologies, which include difficulty in implementing control, high cost, and the complexity of the design with high distortions for the used topologies with the boost converter, affecting the efficiency and performance of the converter in various power applications [6], [22]- [24]. Moreover, the proposed design was modified to improve the performance since PF and THD showed 0.9999 and 2.61%, respectively, which is better than those who adopted the same topology as our work in [21], [25].…”

The AC line input voltage is frequently rectified by single-phase diode rectifiers and filtered using sizable electrolytic capacitors. The capacitor draws current in brief pulses, so harmonics distort the line current, resulting in high losses. Harmonics and line current distortions harm the unity power factor and efficiency. This article adopts a simple single-stage AC-DC converter with a high-power factor and low total harmonic distortion. The PI hysteresis current control was utilized to reduce the total harmonic distortion and increase the power factor at full load. The PI controller was added to the outer voltage loop to regulate the output voltage. Ziegler-Nichol's tuning method was used to determine the controller gain levels. Simulation results were obtained for the AC-DC converter at a constant switching frequency to show the benefits of the proposed control method, which has a low total harmonic distortion and a high-power factor compared with cases without a controller. The proposed control method is accurate and efficient for achieving the power factor correction converter. Besides, the proposed control was stable during dynamic and steady-state responses.
