Abstract :
The battery test requests its system converter to output excellent charging/discharging current. According to the special request, this paper designed the main circuit of current mode PWM converter, and put forward a loop-locked control method based on dq coordinate conversion to SVPWM converters in the power accumulator battery testing system. The set can output low ripple and fast response testing current in a wide adjustable range and operates in high power factor. It delivers the power accumulator´s energy to the power grid without harmonic solutions and increases the transform efficiency by SVPWM and get high power factor and high dynamic response quality by dq coordinate conversion.
