Elevator inverter principle (b)

Typically, the voltage and frequency fixed frequency alternating current is converted to a variable frequency AC voltage or a device called a "drive." In order to generate a variable voltage and frequency, the device is first necessary to convert AC power to DC (DC), this process is called rectification. The direct current (DC) is converted into alternating current (AC) of the device, its scientific term for the "elevator inverter" (elevator inverter). General elevator inverter is the DC power elevator inverter is a certain fixed frequency and constant voltage power elevator inverter. For the adjustable frequency elevator inverter, voltage adjustable frequency elevator inverter we called. elevator inverter output waveform is an analog sine wave, is mainly used in three-phase induction motor drive with, also known as elevator inverter. Mainly used in the instrumentation for the detection devices require a higher variable frequency wave elevator inverter, to sort out the waveform, you can output standard sine wave, called the variable frequency power supply. Frequency power elevator inverter prices are generally 15 - 20 times. Since the elevator inverter device generates a voltage or frequency changes in the primary device called "elevator inverter", so the product itself is named "elevator inverter", namely: elevator inverter. elevator inverter can also be used in home appliances products. Use the elevator inverter home appliances products, not only motor (such as air conditioning, etc.), as well as fluorescent lamps and other products. elevator inverter for motor control, either change the voltage, but also can change the frequency. But are used primarily for regulating fluorescent lamp elevator inverter power supply frequency. Used car battery (DC) to produce alternating current devices "elevator inverter" name for sale. The working principle of the elevator inverter has been widely used in various fields. Such as computer power supply, in the application, the drive for inhibiting reverse voltage, frequency fluctuations and power of instantaneous power.
