Here is a video that shows you the main features of ATO single phase frequency converter and how you can use it to effectively and safely power electric equipment.

Tips: Why does the aircraft use 400Hz power?

The frequency of AC power supply is usually 50Hz or 60Hz. Most of the countries in Asia and Europe adopt the electricity grid in the frequency of 50 Hertz. The United States, Japan, Canada, Taiwan in China, Brazil, the Philippines, Saudi Arabia and other countries adopt the electricity grid in the frequency of 60 Hz.

Then, why is the power source of the airplane 400Hz? Originally, if the frequency of the system is higher, fewer copper and steel materials will be used for the generator and transformer. Accordingly, the weight is lighter and the cost is lower. The shortcoming is that inductive reactance of the electrical device and circuit increases, the capacitive reactance decreases, the loss increases, and the transmission efficiency decreases. Conversely, the low frequency will increase the amount of materials used in electrical equipment, increase the weight and cost. Therefore, 50Hz and 60Hz are not suitable.

There is a well-known saying in the aviation industry: Struggle to decrease every gram! Therefore, the aviation motor is required to have a high frequency, so as to reduce the volume and decrease the weight. However, the electrical transmission line on the plane is not too long, thus the loss is not the main contradiction. Therefore, 400 Hz power supply is the choice.
