Sažetak
Today, three-phase voltage source converters (VSC) are connected to the grid through LCL-filters. This is because the LCL-filters can achieve higher damping than L-filters for the same volume, i.e. price. For the purposes of the LCL-filter design and optimization procedures usually all nonlinearities of the converter are neglected. The dead-time is a safety measure used to prevent the simultaneous conduction of semiconductor switches in the same phase leg of a given converter. Essentially, it represents a nonlinearity introduced into the system. This paper focuses on the deadtime concept and its influence on three-phase VSC performance in steady-state. The influence of dead-time is analysed by comparing harmonic spectrums of the converter AC voltage and the current at the point of common coupling for various values of dead-time. The use of simulation model is a simple and straightforward way to carry out this analysis. The simulation results, obtained for the case of zero dead-time and double-edge naturally sampled pulse width modulation (PWM), are numerically validated by comparing harmonic spectrums with well-known analytical solutions for the selected PWM strategy. The results presented in this paper clearly show that the dead-time should not be omitted from the harmonic spectrum analysis, and from the filter design and optimization procedures. This indicates that similar analysis should be done for other nonlinearities present in the system.
