Dead-time Compensation Strategy based on DSP Controller
Peng Deng-feng · IEEE Transactions on Power Electronics · 2008
With the impact of dead-time and flywheel diodes on output voltage in an inverter system considered,on the view of integral section,double Fourier transform is used to analyze the output voltage of a single-phase frequency-doubled three-level SPWM(Sinusoidal Pulse Width Modulation) inverter bridge quantitatively.A simple compensation method is studied based on the DSP controller and the theory is described in graph.Both the simulation and experiments validate the analysis.The research results show this method is very simple and can be carried out easily,and also a excellent effect is achieved.
