Selective Harmonic Elimination Control for Cascaded Digital Power Amplifier
2020 IEEE 1st China International Youth Conference on Electrical Engineering (CIYCEE), 2020In this paper, the selective harmonic elimination (SHE) strategy for cascaded digital power amplifier is derived and proposed. To solve the problem of slow iteration speed or even non-convergence of the traditional iterative method when the number of levels or the number of harmonic elimination equations is large, a new solution method based on ...

Design equations for selective harmonic elimination and microcontroller implementation
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014The paper presents an analytical approach to find switching angles for an optimal PWM signal. 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 with expensive software and solution time can be a ...
