Inverters, how do they work?

Power inverter circuit and power inverter device


The term "inverter" essentially refers to an electronic device (power inverter circuit) that converts DC (direct current) to AC (alternating current), but can also refer to power inverters used in home appliances such as air conditioners and washing machines . Power inverter is also responsible for controlling the speed and torque of the electric motor.

 


Take air conditioning as an example. An air conditioner without an inverter will pause when it gets too cold and only resume when it gets too hot. This is very inefficient due to unstable room temperature and high power consumption.

 

For air conditioners equipped with frequency conversion, when cooling starts, the motor will rotate at high speed to drive the fan to rotate. When the temperature is close to the set value, the fan will gradually slow down and continue to run, gradually changing. This prevents wasted movement and ensures more energy-efficient operation compared to air conditioning that just turns on and off.

 

Therefore, the term "inverter" is often used in the field of home appliances. In recent years, more and more induction hobs are operating with very high frequency alternating current from 20 kHz to 90 kHz, and inverters have also played an active role; this can only be achieved by changing the frequency using a power inverter device.

 

Pure sine wave inverters generate a unique sine wave that ensures smoother and more efficient operation of home appliances including: laptop and cell phone chargers, power tools, heaters, kettles and more. Now with a wider input voltage range for 24V and 12V inverters, they can work comfortably anywhere, even under the harshest conditions. Not to mention, they have multiple levels of protection including overload, short circuit and over temperature and load controlled cooling fans

 

With our pure sine wave inverter, you can use your electrical equipment anywhere and get the same type of 240 volt power that you have at home.

 

You can also buy a portable inverter for your car that lets you use the car battery to power small household appliances.

Electric motors are found in most of the equipment we use for work, such as small electronics, vehicles and office equipment. These motors require electricity to operate. Matching the speed of the motor to the desired process is critical to avoid wasting energy. In factories, wasted energy and materials can pose a risk to the business, so power inverters are used to control electric motors, increasing productivity and saving energy.
