Now DSK elevators are used to control the inverter, when the inverter fails a lot of people will cause inconvenience, if the maintenance staff can correctly understand the principle of elevator inverter, then maintenance has been easy.

We use the power is divided into AC power and DC power supply, the general DC power is mostly from the AC power transformer through the transformer, rectifier filter obtained. AC power is about 95% of the total power used by people. Whether for home or in factories, single-phase AC power supply and three-phase AC power supply, the voltage and frequency according to the provisions of each country has a certain standard, as China's mainland regulations, the direct user single-phase AC 220V, three-phase AC The voltage of the electric wire is 380V, the frequency is 50Hz, the voltage and frequency of the power of other countries may be different from the voltage and frequency of our country, if single-phase 100V / 60Hz, three-phase 200V / 60Hz and so on.

In general, a device that converts a commercial AC voltage with a constant voltage and frequency to a variable voltage or frequency AC power is called an "inverter." In order to produce variable voltage and frequency, the device must first convert the power of the AC to DC. The device that converts direct current (DC) to alternating current (AC) is an inverter.

Inverter is the general inverter DC power inverter for a certain fixed frequency and a certain voltage inverter. For the inverter is adjustable frequency, adjustable voltage inverter we call inverter. Inverter output waveform is an analog sine wave, mainly used in three-phase asynchronous motor speed control, also known as inverter. For the main use in the instrumentation of the waveform of the waveform of the higher requirements of variable frequency inverter, to the waveform finishing, you can output the standard sine wave, called the variable frequency power supply. Inverter can also be used for home appliances. In the use of inverter products, not only motor (such as air conditioners, etc.), as well as fluorescent lamps and other products.
