Vector control of three-phase inverter
Vector control uses coordinate transformations (such as Clarke and Park transformations) to convert the three-phase motor currents into a two-coordinate system (d, q), enabling better regulation of the motor's internal dynamics. . Scalar control, commonly known as Voltage/Frequency (V/f) control, offers a simple, cost-effective method for motor control but is limited in its precision, torque regulation, and dynamic response. In contrast, vector control faster response times, improved speed and torque accuracy, and reduced. . This paper proposes a transformation matrix to generate two phase reference voltage signals for Four Switch Three Phase Inverter (FSTPI) using vector control. The three phase voltages are applied by three pairs of semiconductor switches vu+/vu−, vv+/vv and vw+/vw with amplitude, frequency − − and phase ang e defined by microcontroller calculated pulse p tterns. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the. .
