Features Inverter (Inverter) Model : SG-VB-4T2R2GB/2.2kW, 3HP, 3 phase 380VAC

DC Input Power:

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

Switching Circuit (IGBT, MOSFET):

• Uses switching devices to quickly switch power supply, creating alternating current signals.
• Controlled to switch in a three-phase sequence (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 from 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, precise motor speed control and more energy-efficient than conventional on-off systems.

• Reduces starting surge currents for motors.
• Suitable for loads requiring high torque. Applications of three-phase inverters, such as water pumps, fans, conveyor belts.
• Industrial machinery
• HVAC systems (heating and cooling in buildings). Advantages of using Inverter Three Phase, energy savings.
• Extends motor lifespan.
• More precise system control.
• Reduces wear and tear from traditional motor starts.
