“…He compared the feedback signal of output voltage and errors of the reference voltage and finally adjusted the output voltage with PI controller (Dhinesh & Saravanan, 2020). He modified Flyback converter without RHPZ in its duty-cycle-to-load-voltage transfer function which could be applied for many systems (Goudarzian et al, 2022). He worked on the performance analysis of open loop control and closed loop control using PID controller for a flyback converter (Jayaram, 2022).…”

Power electronic converters have a important function in effectively converting and managing electrical power and mainly used in low power applications. Owing to the low cost, quick dynamic response and compacted size of DC-DC converter, their usages are increasing in the field of telecommunication, control system, switched mode power supplies and renewable energy interface. Flyback Converter is a versatile and adaptable DC-DC converter that can be used in a wide range of power system applications. In this paper, the transients response of flyback converter is improved using the Sliding Mode Controller. The proposed scheme of SMC which is implemented in this work comprises on linear and nonlinear controllers. The linear controller is implemented by using PI and nonlinear part of controller with hysteresis. The points at which hysteresis control turns ON and OFF are determined by inductor current ripple. Proposed controlled scheme for Flyback converter is simulated using MATLAB®/SIMULINK® software. Moreover, for validation the results, The flyback converter is designed using the Dual loop PI controller. Simulation analysis of two controllers dual loop PI and SMC for flyback converter confirm that the performance of SMC is better than the linear controller here in terms of settling time, rise time, overshoots, line and load variations.

“…Push-pull converters are typically unsuitable for FC power generation, especially at high power, due to the difficulty in overcoming transformer saturation [38,39]. The modified fly-back converters [69,70] suffer from voltage stress across the rectifier diode. The single winding carries a current, operates in a discontinuous mode (to avoid core saturation), and has high off-state voltage and poor core utilization.…”

This review emphasizes the role and performance of versatile DC-DC converters in AC/DC and Hybrid microgrid applications, especially when solar (photo voltaic) PV is the major source. Here, the various converter topologies are compared with regard to voltage gain, component count, voltage stress, and soft switching. This study suggests the suitability of the converter based on the source type. The merits of a coupled inductor and interleaved converters in micro gird applications are elucidated. The efficiency and operating frequencies of converts for different operating modes are presented to determine the suitable converters for inductive and resistive loads. The drawbacks of converters are discussed. Finally, the mode of operation of different converts with different grid power sources and its stability and reliability issues are highlighted. In addition, the significance of the converter’s size and cost-effectiveness when choosing various PV source applications are discussed.

This paper proposes a solar-powered isolated DC–DC converter for high-power applications. The main aim of this paper is to achieve voltage regulation in the output side of the converter and to integrate a lossless active clamp flyback circuit (LACF) to compensate for the high-voltage issues that arise from one-stage DC–DC converters. Hardware is developed with a power rating of 2 kW to test the performance of the proposed circuit. The circuit is designed using low-voltage devices and features such as soft switching and regeneration due to the LACF, which enhances efficiency. A novel luminous control algorithm is presented to improve the converter performance. The proposed circuit’s performance and feasibility are compared with existing converter parameters, such as the number of components in the circuit, voltage rating, and regeneration.
