A common technique employed to eliminate switching harmonics is programmed SHE (Selective Harmonic Elimination) which requires the solution of a set of nonlinear equations. Typically, the method calculates the switching angles for each modulation depth offline using iterative computations and programmed into a digital processor. These values are recalled on(More)
The paper presents an analytical approach to find switching angles for an optimal PWM signal and its implementation using an ordinary microcontroller. The solution is in closed form that eliminates the need for numerical solution to find the transition angles. The disadvantage in iterative computation is overhead in computational effort as it requires a PC(More)
