Pulsewidth modulation (PWM) techniques are employed in voltage-source inverters to produce a variable output voltage containing the least possible harmonic distortion over a wide frequency range. To achieve these objectives, compromises are made in terms of control circuit complexity, smoothness of inverter operation, and overall system reliability. The delta modulation (DM) technique fulfills the aforementioned performance requirements with a minimum of circuit complexity, smooth inverter operation and with improved system reliability.
