Reference design for a 22kW industrial motor drive for three-phase 400 V AC grids.
The REF-22K-GPD-INV-EASY3B can be utilized for each low-powered motor management in addition to high-power functions.
The reference design REF-22K-GPD-INV-EASY3B from Infineon is an industrial motor drive for three-phase 400 V AC grids and has a nominal energy of twenty-two kW. It features a energy module, present sensor, gate driver IC and a 1.7 kV SiC-MOSFET. The reference design can be utilized for each low-powered motor management in addition to excessive energy functions akin to conveyor belt and compressors, and so on. The reference design additionally contains a software program that permits full management and communication by way of contact display screen and PC-GUI. The reference design can take 3ϕ enter between 380 – 480 V and supply a variety of output from 0 – 456 V with a rated present of upto 45A. The reference design is pretested and is very customisable. The drive is appropriate for all kinds of functions akin to motor drives, servo drives, UPS methods, pumps, conveyor belt, Air-con compressor, and so on.
The reference designed could be divided into 5 separate boards: Energy board, EMI filter, Excessive-voltage logic board, Low-voltage interface board, DC-link board. This makes the reference design extremely customisable with respect to specification and measurement. Moreover, it permits for higher isolation between completely different sub-systems making the reference design safer and extra dependable.
The reference design makes use of two microcontrollers: one for management and one for communication. The communication microcontroller allows the touchscreen. The board additionally supplies the potential to interface with exterior sensors, akin to a high-resolution rotor velocity sensor, high-resolution rotor angle sensor, temperature sensor, and so on. The reference design is an air-cooled system using as much as 3 followers. The followers can robotically modify cooling by adjusting the circulate price.
The AC voltage is rectified by way of the uncontrolled diode full bridge. The inrush present is restricted by pre-charge circuitry. The rectified AC voltage is stabilized by a DC-link capacitor financial institution. The IGBT six-pack permits for the modulation of a three-phase output voltage/present which could be assorted by way of its amplitude and frequency. The reference design is appropriate for each low-powered in addition to high-powered functions akin to driving machines, conveyor belts, lifts, and so on.
The reference design could be divided into 5 separate boards: – Energy board, EMI filter, Excessive-voltage logic board, Low-voltage interface board, DC-link board.
Energy board: The facility board is used for powering all the opposite sub-boards. It homes the principle DC-DC converter and the gate driver.
DC-link board: The reference design makes use of a number of electrolytic capacitors. The DC-link board is used to individually homes the capacitor thus permitting larger stage of design freedom and a compact design of the inverter.
EMI-Filter board: The EMI filter board supress the RF noise generated in the course of the operation.
Excessive-voltage logic board (FELV board): This board could be thought of because the mind of the reference design, all logic capabilities required to manage the drive motor are applied on the high-voltage (HV) logic board.
Low-voltage logic board (SELV board): This board maintain all of the communication options of the reference design. It allows connectivity choices akin to EtherCat, USB 2.0, WLAN, Bluetooth, RS485 and Excessive-Velocity CAN.
This reference design has been examined by Infineon. It comes with required design assets akin to Gerber recordsdata, schematics, BoM, and so on.
