Abstract: Passive filters are generally preferred in power converters to nullify the high-frequency harmonics caused by pulse width modulation (PWM). Employment of passive filters is an effectual solution that can be used to attain harmonic mitigation to a greater extent mainly because filters are put forward to increase the efficiency. Isolated DC-DC converters were usually used topologies. In power electronics application half-bridge converter is one of the suitable converters. Stress on the switches can be minimized by using the half-bridge converter. Hence, half bridge converter is modified based on the application and LLCCLL filter is connected at the input side to reduce the input side harmonics. With these notes taken into account, the objective of this paper is to design a new topology of passive LLCCLL filter for harmonic mitigation. Thus, it also improves the power factor of the load. Hence, simulation is carried out in P-SIM software and hardware implementation will carry out in the medical x-ray equipment to measure the reduction of the harmonic level
