S-073N 3BHB009884R0021 High Voltage inverter is a power electronic device used to change the frequency and amplitude of AC motor supply. It can control the speed of the motor by changing the power supply frequency of the motor, so as to realize the speed regulation and energy saving of the motor. The application range of high voltage inverter is very wide, including power, metallurgy, petroleum, chemical, cement, elevator and other industries.
A high-voltage inverter is a power electronic device used to change the frequency and amplitude of the AC motor supply. It can control the speed of the motor by changing the power supply frequency of the motor, so as to realize the speed regulation and energy saving of the motor.
S-073N 3BHB009884R0021 The basic structure of the high voltage inverter includes four parts: rectifier, intermediate DC link, inverter and controller. The rectifier converts the input AC into DC, the intermediate DC link is used to smooth the DC, the inverter converts the DC into AC with adjustable frequency and amplitude, and the controller is used to control the operation of the inverter.
S-073N 3BHB009884R0021 During the operation of the HV inverter, the controller generates the corresponding control signal according to the set frequency and amplitude requirements, converts the control signal into the modulated wave through the modulated wave generator, and then loads the modulated wave to the power semiconductor device of the inverter through the drive circuit. The power semiconductor device will produce the corresponding switching action under the action of the modulating wave, and convert the direct current into the alternating current with adjustable frequency and amplitude, so as to realize the speed regulation and energy saving of the motor.
ACS2000 High Voltage inverter how to change the phase module. It can be connected directly to the grid, you can also connect to the grid via a separate double-winding transformer or integrated transformer and is suitable for direct grid connection or with input isolation transformer applications
