the in the technology has enabled better and more efficient air conditioner or heatpump to be deployed..
In AC, the stator of the motor has windings that are designed in such as way that rotating magnetic field is produced when AC voltages are applied to the windings..
In DC motor used in DC inverter air conditioner or heatpump, the rotor of the motor is constructed using permanent magnets with windings on the stator..
By the use of micro controller, The windings of the motor are connected to the power electronics control that determine the speed of the motor..
When purchasing your unit, check with the personnel whether the compressor and fans used are DC type before making decision of buying the conditioner or heatpump..
The electronics control is the most complicated part of DC inverter system hence making it one of the most costly component of the conditioner, the other part being the compressor..
Being converter means that the correction for this design is able to correct the factor of the equipment to more than 98% compared to the solution based on LC filter..
The software is written in such way that proper signals being used to ON or OFF each transistors at correct timing depending on the feedback such as the position of the relation to the motor and the voltage levels detected..
DC of the compressor will receive close to phase voltage that turns the ON.
By varying the power supplied to the motor through the switching of the transistors, The speed of the motor can be controlled from low to high.
