This paper presents a novel modulation scheme known as the nonzero staircase modulation scheme for switching DC-DC boost converters. This modulation scheme generates two distinct pulse trains/firing signals when a 50 Hz nonzero staircase modulating signal is compared with a 1.5 kHz triangular wave signal. Unlike the conventional modulation schemes, the proposed novel modulation scheme provides two distinctive trains of pulse-width modulated signals for mitigating low and high harmonics. It also possesses 0.56% total harmonic distortions (THD) of the output voltage waveform system, a power output of 4591 W, and THD of 1.12% in the DC-DC boost converter system. It has a simple design and low power loss of 209 W. The proposed scheme enables the single switch boost DC-DC converter used to have an efficiency of 96%. The proposed scheme can be applied in single switch or double switch boost DC-DC converter based-hospital equipment.

Square Wave

This paper proposed a novel single-stage square wave buck-boost inverter (SWBBI). The proposed inverter is designed by using dual buck-boost converters. The input DC voltage of the proposed inverter can be either stepped-down or stepped-up in square output voltage waveform depending on the duty-cycle applied for each buck-boost converter. This characteristic is not found in conventional voltage source inverter where the output voltage is always lower than the input DC voltage. The proposed inverter is analyzed by a series of simulations using MATLAB/Simulink as well as experiments by using different values of duty-cycle. A conclusion about the feasibility of the proposed inverter is given by comparing the simulation and experimental results.
