In fact, the drive can be used in addition to changing the frequency of the AC power supply, but also can be used to change the AC motor speed and torque. In this application environment, the most typical structure is a three-phase inverter secondary voltage source inverter. The drive through the semiconductor switch and a pulse width modulation (PWM) to control the voltage of each phase. In addition, the drive can also be in the aerospace industry. For example: an aircraft electrical equipment typically require AC 400Hz, and the AC is generally used on the ground 50Hz or 60Hz. Therefore, when the aircraft parked on the ground, you need to use the inverter AC 50Hz or 60Hz AC on the ground into a role for aircraft use the drive to 400Hz? The main drive by the rectifier (AC to DC), filtering again rectified (DC to AC), brake unit and the drive unit, a detection unit consisting of micro-processing unit or the like. 1. Why is the rotation speed of the motor can be freely changed?
