This paper presents the simulation and design of Neutral Point Type (NPT) converters that have been used to increase power factor near one (1) which is unity. The circuit of the simulation has been design using Simulink MATLAB. The circuit was set to 50 kHz to generate Pulse Width Modulation (PWM) with carrier signal and comparing it with the reference signal. By adjusting the capacitor in the main circuit, the result of the simulation shows that the input current and voltage were in phase which is unity power factor while the output current and voltage produced having a low ripple. Thus, the simulation shows that the Neutral Point Buck type converter is suitable for maximizing power factor close to unity (1).
