Abstract
A nonlinear compensation method for matrix converter is proposed to compensate the voltage error between the reference voltage and actual output voltage. The output voltage error caused by voltage-based commutation process is analyzed, and the parasitic capacitor effect of the matrix converter on a forced commutation process is investigated. It is found that the parasitic capacitor effect could reduce the total output voltage error caused by the commutation process, and it makes the output voltage error relate to not only the direction of the load current but also the magnitude of the load current. The voltage error caused by the voltage-based commutation process is obtained considering the switching pattern, and then, the general function of the total voltage error is obtained considering the on-state voltage drop of the switching devices. The effectiveness of the compensation method has been verified by passive <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$R$</tex> </formula> – <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$L$</tex></formula> load experiments and induction motor vector control experiments.
