Abstract
- This paper presents an analytical solution to characterize harmonic behavior of digitally controlled H-bridge inverter output with two nonlinear effects: sample delay and dead-time. The effect of sampling frequency in uniformly sampled pulse-width modulation (PWM) is discussed, including spectral analysis and compared with the analog modulated PWM. The effect of dead-time on the rising and falling edge of digitized PWM inverter error output is derived in time-domain. The double Fourier integral solution is used to develop the accurate mathematical expressions for the switched output waveforms. The integral solutions are obtained using Jacobi–Anger expansions. The analytical results are verified with simulation using PSCAD and experimental results. [ABSTRACT FROM AUTHOR]
