Abstract
In a real time control of a pulse width modulated inverter, equations are developed relating switching angle, system parameter or parameters and output harmonics. Constants are stored which define a preferred angle for each switching event. Switching angles are calculated in real time by solving the equation in accordance with the value of the system parameter.
