Features Inverter (Inverter) Model : SG-VB-4T015GB/18R5PB/15kW/20HP/3 phase 380VAC

DC Input Power:

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

Switching Circuit (IGBT, MOSFET):

• Uses switching devices to rapidly switch power supply, generating alternating current signals.
• Controls the switching sequence in 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 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, and industrial machinery.
• HVAC systems (heating-cooling in buildings).
• Energy savings from using Inverter Three Phase.
• Extends motor lifespan.
• More precise system control.
• Reduces wear and tear from traditional motor starts.
