Top 11 Most Important Benefits of Inverter Technology on Home Appliances

Inverter technology (also known as frequency conversion technology) is applied to control the power of devices to avoid unnecessary energy waste. Inverter primarily relies on advanced circuit boards manufactured and developed by Japan. The basic principle of Inverter technology is based on controlling each frequency oscillation according to the design of the circuit board inside.

Inverter technology is temperature-controlled based on the natural temperature changes in the room. When the desired temperature is reached, the inverter technology will automatically adjust its output to ensure temperature maintenance, making the operation more efficient. Simply put, when the device requires more energy, Inverter technology will provide more energy; when less energy is needed, it will supply less energy. The Inverter is always busy but consumes less energy or more energy depending on the air temperature and the set level in the thermostat. The speed and power of the compressor are adjusted accordingly.

Inverter provides an AC voltage from DC power sources, useful in supplying energy to electrical devices using AC power.

Advantages of inverter technology:

• Energy saving: With the principle of frequency reduction, controlling oscillation has maximized energy savings for the device.
• This will help consumers reduce electricity costs.
• Maintaining stable temperature for the machine: With inverter technology, only reducing vibration, changing the frequency makes the motor operate slower, helping the machine maintain a more stable temperature. The machine will not get too cold or too hot, making the device more durable.
• Smooth, gentle operation: When the machine operates, the motors can produce unpleasant noise. However, with inverter technology, the motor operates stably without generating loud noise, making it smooth and comfortable for consumers to use.
• Longer-lasting electrical devices, higher durability.

However, Inverter technology devices are relatively expensive compared to regular types, and the repair costs are also quite high, so not every family chooses to buy them.

The operating principle of Inverter technology is relatively simple. First, the inverter uses 1-phase or 3-phase power that has been rectified and filtered into flat DC power.

This conversion process is achieved through a Diode rectifier and a capacitor. This ensures that the power factor (Cosphi) of the inverter system is always guaranteed to be no less than 0.96 and is independent of the load rating.

Next, this DC voltage is converted (inverted) into symmetrical 3-phase AC voltage. This process is currently performed through IGBT (Insulated Gate Bipolar Transistor) using Pulse Width Modulation (PWM) modulation method.

Thanks to the advancements in microprocessor technology and semiconductor technology, the switching frequency can reach the ultrasonic frequency range, providing smooth operation, reducing motor noise, minimizing losses on the motor iron core, and saving energy during operation.
