Abstract
The Specific Harmonic Elimination Pulse Width Modulation (SHEPWM) is used in a neutral-point-clamped converter. The SHEPWM is implemented in a DSP chip by software. Transient current between different PWM in open loop operation is small. Simulations of close loop control show that work of SHEPWM in dynamic process requires the voltage vector rotate steadily while the requirement on its length change is not so strict.
