Abstract：In random pulse width modulation (RPWM), the instantaneous switching frequency of inverter is required to be distributed in a wide frequency range for better randomness. However, when the switching frequency continues to be high, the switching loss will be increased. When the switching frequency continues to be low, the increase of output current ripples will be introduced. The existing selective harmonic elimination method in RPWM cannot effectively control the switching frequency of inverter as needed in the process of random spread-spectrum. In this paper, a novel hysteresis random spread-spectrum method in RPWM selective harmonic elimination for single-phase inverter is proposed. With the reasonably chosen random number (k) according to the relationship between k and switching frequency in RPWM, the proposed method can guarantee that the instantaneous switching frequency is randomly distributed over a wide range and the average switching frequency can be controlled within a preset range. When the current ripples are large due to low switching frequency in RPWM selective harmonic elimination method, the average switching frequency can be increased to reduce it.
