This paper presents a technique for the variation of hysteresis band in delta-sigma modulation. A sinusoidal, and a random hystersis band are combined to achieve an optimal performance in terms of constant switching frequency and the harmonic spikes. The sinusoidal hysteresis band technique produces a constant switching frequency while the random hysteresis band suppresses the harmonic spikes. The effects of various variations of hysteresis band on the harmonic spectrum characteristic were described. The technique is experimented in a single-phase inverter and the harmonic peaks and the distortion of output voltage were used to measure the performance of the proposed technique.
