Four-quadrant inverter
FGI is an early professional manufacturer engaged in the research of hoist (four-quadrant or energy feedback type) inverter in China. The high-voltage four-quadrant (hoist) inverter adopts advanced vector control technology. The main difference between vector control and traditional V/F control is that vector control can separate the reactive current from the active current (torque current), and can automatically adjust the active current according to the change of the load during lifting process to make the output torque reach the best working condition which can output 2.5 times of the rated torque.
1. It can perform energy feedback, and the circuit structure of its power unit is shown in the figure below. Both the rectifier side and the inverter side use IGBT power devices, and the control method adopts SVPWM technology.

2. When the motor is in the driving state, the energy flows from the power grid to the motor through the rectifier circuit and the inverter circuit, and the inverter works in the first and third quadrants. The input voltage and current waveforms are shown in the figure below.

3. When the motor is in the power generation state, the energy generated by the motor is fed back to the busbar voltage through the diode on the inverter side. When the DC busbar voltage exceeds a certain value, the energy feedback control part of the rectifier side starts to invert the DC to AC. The inverter voltage phase and amplitude feed energy back to the grid. The inverter works in the second and fourth quadrants. The input voltage and current waveforms are shown in the figure below.
