The fly-back converter is a popular power electronics converter for regulated power supply due to its simplicity and efficiency. This research paper concentrates on designing a flyback converter for a solar pump controller, considering input voltages from 400V to 1200V DC and output voltages of 15V, 5V, and 3.3V. Implementing the Cascode topology in the converter aims to increase controller performance, minimize losses, and improve voltage control. The Cascode technique improves overall efficiency by optimizing switching characteristics and reducing voltage stress on switching devices. The research analyses the behavior of a flyback converter in Discontinuous Conduction Mode (DCM) for a solar pump controller where the inductor current totally discharges after each switching cycle. The simulation results represent the converter in DCM using the Cascode technique is efficient, generating required output voltages and accurate voltage control over a broad range of input voltage changes. The results are beneficial for engineers and academics working on high-voltage isolated power supply, particularly for solar pump control applications. The paper has a sense on design considerations, simulations, and analysis of flyback converters, with a focus on improving the performance of solar pump controller.
