The thesis will be established as digital Inverter with analog power board and DSP kernel. We can accomplish effective ac motor control with VVVF mode by powerful arithmetic ability of DSP. Furthermore, we can obtain rotor speed by calculating the feedback voltage and current of motor from sensors. We adopt the new integrator scheme to replace traditional pure integrator to solve the dc drift and initial value problems. Meanwhile, we can compensate the voltage distortion caused by dead time to decrease current ripple via judging the direction of current. Because we have modulized our circuits, it is very convenient that we can achieve modern control theories by software modification only.
