This work introduces a novel topology of active buck power factor corrector rectifier operating in continuous conduction mode and producing a voltage wave with multiple levels across the rectifier. The offered redesigned packed U-cell rectifier structure eliminates the grid side capacitor and load side inductor for filtering due to CCM operation. The suggested rectifier provides two separate outputs that can link two specific loads at various switching options. The two output ports are helpful to have a 5-level voltage wave shape across the contacts of the rectifier. The voltage harmonics are reduced when different voltage levels are produced, directly influencing the grid current harmonic contents. The suggested rectifier's low switching frequency distinguishes it from further buck converters that considerably reduce switching losses and excessive switching frequency-related concerns. From an AC supply perspective, the rectifier boosts the voltage, but the output DC voltage can be divided into two parts, leading to the functioning in buck mode. The MATLAB Simulink outcomes are given and examined to validate the suggested five-level buck rectifier's effective operation and good dynamic performance.
