Features Inverter (Inverter) Model : SG-VB-4T18R5GB/022PB/18.5kW/25HP/3 phase 380VAC

DC Input Power:

• It may come from a battery, solar panel, or converted from household AC power to DC through a Rectifier circuit.

Switching Circuit (IGBT, MOSFET):

• Uses switching devices to rapidly switch power supply, generating alternating current signals.
• Controls the switching sequence according to three phases (R-S-T or U-V-W).

Waveform Control (PWM - Pulse Width Modulation):

• Uses PWM technique to create an output signal with a waveform closest to sine wave.
• Can control the speed of AC motors by adjusting the frequency of PWM.

Output Result: Three-phase alternating current that can be used with various loads such as three-phase motors. Advantages of using a three-phase inverter, accurately controlling the speed of AC motors and saving more energy than conventional on-off systems.

• Reduces surge currents during motor startup.
• Suitable for loads requiring high torque, such as water pumps, fans, conveyor belts in three-phase motor systems.
• Industrial machinery
