The demand for electricity in the country is increasing due to a growing population. To meet peak load demands, renewable energy sources such as A.C. inputs can be used in conjunction with conventional sources. However, the widespread use of nonlinear electronic equipment has led to power quality issues in grid-connected systems. This is because power electronic converters inject harmonics into the system, causing various problems. In this study, the Boundary Conduction Mode (BCM) boost and Power Factor Correction (PFC) converter were used to improve power quality. BCM DC-DC converters are high-frequency converters that regulate unregulated D.C. power and reduce the voltage stress on MOSFETs additional DC/DC converter by lowering the DC bus voltage. Interleaved pulse-width modulation (PWM) is employed to manage the switches. Reducing the entry and delivery ripple currents and allowing for a decrease in output capacitance. The three basic configurations of DC-DC converters are buck, boost, and buck-boost converters. A buck-boost converter can either decrease or increase the input voltage, while a boost converter is commonly used in renewable energy systems due to their low and unregulated output voltage. The output evaluate through simulation and hardware implementation, resulting in significant improvements in power factor.
