What is inverter technology?

Inverter technology is a modern solution that enables precise control and adjustment of electrical device power by varying the frequency of the current. Thanks to its ability to optimize performance, this technology helps save energy, reduce noise and extend equipment lifespan.

The operating principle of an inverter is based on converting voltage from AC (Alternating Current) → DC (Direct Current) → AC with a variable frequency, allowing flexible control of motor speed or temperature.

Today, inverter technology is widely applied in various fields such as refrigeration, industrial automation, transportation, and renewable energy due to its superior efficiency and significant energy-saving capabilities.

Operating principles of inverter technology

Inverter technology operates through three main stages::

AC to DC rectification: Alternating current from the power grid is rectified into smooth direct current using a diode bridge rectifier and capacitor.

The DC voltage is processed through an IGBT (Insulated Gate Bipolar Transistor) system with Pulse Width Modulation (PWM), generating an AC output with variable voltage and frequency.

Smart control: The controller manages the voltage conversion and optimizes the operating efficiency.

Thanks to modern microprocessor technology, inverter switching frequencies can reach ultrasonic levels, minimizing noise and reducing energy loss.

Advantages of inverter technology

Compared to traditional devices, inverter technology offers several outstanding advantages:

+ Optimal energy saving

The inverter automatically adjusts power output, preventing unnecessary energy waste.

It can reduce electricity consumption by 30–50% compared to non-inverter devices.

+ Smooth and quiet operation

The inverter maintains operation at the lowest necessary power, ensuring smooth motor function and noise reduction.

This is especially beneficial for air conditioners, refrigerators, elevators, and industrial equipment that require quiet operation.

+ Extended equipment lifespan

This technology reduces mechanical wear by controlling speed and ensuring soft start operation.

Inverter-based equipment avoids damage caused by sudden startup currents, resulting in greater durability.

+ Efficient temperature control

For air conditioners, refrigerators, and microwave ovens, inverter technology helps maintain stable temperatures, avoiding frequent ON/OFF cycles. This improves energy efficiency and enhances overall device performance.
