Clarke-transformer circuit design

Abstract

My research talk about the principle of Clarke transformation for three-phase symmetric currents and the implemented electric circuit as well. This article shows three measurements of 2.2 kW induction motor’s current after the mathematical transformation. This motor is powered with custom two-level voltage source inverter, wich can work with standard driving as well as Pulse-width modulation. This inverter get the DC voltage from half controlled three-phase rectifier. I can change the motor’s voltage and the frequency too. I shows the two-dimensional transformed currents in oscilloscope.
