The matrix alternating control mode of the inverter - LS power generation
VVVF frequency conversion, vector control frequency conversion, and direct torque control frequency conversion are all one of the AC-DC-AC frequency conversion. One of the disadvantages is that the input power factor is low, the harmonic current is large, the DC circuit needs a large energy storage capacitor, and the regenerative energy cannot be reflected back to the grid, that is, it cannot carry out four-quadrant operation.

The principle and function of the power production contactor
The working principle of the power production contact is: when the contact coil is energized, the coil current generates a magnetic field, and the generated magnetic field leads the static iron core to produce electromagnetic attraction to the iron core, and drives the AC contact action, the normally closed contact is disconnected, the normally open contact is closed, and the two are connected to each other. When the coil is de-energized, the electric ...
