三相并网逆变器内模控制的改进型GDPWM算法
A Modified GDPWM Algorithm Based on Internal Model Control for Three-phase Grid-connected Inverters
摘要
Abstract
The internal model control equation of a three-phase grid-connected inverter with a unitary power factor was deduced. The function relationship between the power factor angle and output current at the inverter side was studied. The characteristic of traditional general discontinuous pulse width modulation (GDPWM) was analyzed in detail. A modified GDPWM (M-GDPWM) algorithm with the minimum switching loss was proposed in this paper. Zero-sequence voltage components injected into three-phase sinusoidal reference voltages were generated by comparing instantaneous three-phase sinusoidal reference voltages, or by judging instantaneous three-phase output currents at the inverter side, rather than calculating the power factor angle to minimize switching loss in the traditional GDPWM algorithm. Simulation and experimental results verify the correctness and validity of the proposed M-GDPWM.关键词
