This is How inverter Air Conditioners Work
In recent years, air conditioning with DC inverter has become more popular compared to conventional air conditioning due to its many advantages. Because the compressor uses the most energy in all air conditioning systems, the change in compressor technology has made it possible to use a better and more efficient heat pump or air conditioner.

AC induction motor
In a three-phase AC induction motor, the motor stator has windings designed to produce a rotating magnetic field when a three-phase AC voltage is applied to the windings. The rotor generally has windings that are embedded in iron laminates. As the windings receive power, the magnetic field is produced in the rotor, which causes it to react with the magnetic field in the stator. The rotating magnetic field of the stator draws the rotor with the rotor and tries to follow the trace of the rotating field.

DC brushless motor
In a brushless DC motor used in the air conditioner or the DC inverter heat pump, the motor rotor is constructed using permanent magnets with windings in the stator. There are no brushes or switches compared to a typical DC motor and, therefore, problems such as sparks, brush life, brush residue and electrical noise are eliminated. The motor windings are connected to the controller of the power electronics that determines the speed of the motor with the help of a microcontroller.
Various security and monitoring controls
Various security and monitoring controls are integrated into electronic controls to ensure efficiency and reliability. This type of motor is used in more design due to its better reliability and energy efficiency. Therefore, the main advantages of a DC brushless motor compressor are its quiet operation, its more compact, longer life, its energy saving and better capacity control, which translates into a more comfortable environment for the people who use the equipment. Its use is no longer limited to air conditioners, but also in refrigerators, washing machines, pumps and fans.
In many DC inverters divided without ducts, the indoor fan used is the DC fan instead of the AC fan. Similarly, the outdoor fan used is a DC fan instead of the conventional AC fan. When you buy your device, you should check with the staff if the compressor and fans used are of the DC type before deciding to buy the air conditioner or the heat pump.
DC inverter control circuits
Electronic control is the most complicated part of a DC converter system, which makes it one of the most expensive components of air conditioning, while the other is the compressor. Let’s look at the control circuit of the DC compressor that receives power from a single-phase power supply. There are many variations in the design and we will see a design that uses power factor correction that provides a better power factor.
The first part consists of a DC converter.
The DC converter converts the incoming power source from AC to DC using four diodes that are connected as a bridge. The inductors and capacitors are connected to the converter to reduce the electrical noise introduced into the power supply due to the switching of the transistors. The single-phase power supply is used in the simplified diagram below. If a three-phase power supply is used, six diodes are required to convert alternating current to direct current.
The benefits of DC Inverter technology
- Faster response to variable heating and cooling loads.
- Significantly lower operating costs (up to 50% savings) compared to systems that are not investors.
- Greater comfort since the adjusted temperatures are reached faster.
- Improves the maintenance of design conditions with less temperature fluctuations.
- Lower noise levels, both inside and outside the building.
- Eliminates compressor voltage peaks.
- Less risk of electromagnetic interference with other equipment.
