STDES-LVHP01 [STMicroelectronics]

The main objective of the low-voltage high-current inverter motor control board reference design is to recommend a layout and associated BOM for dedicated applications (this board is not for sale).

The STDES-LVHP01 low-voltage high-current inverter motor control board, coupled with the B-G473E-ZEST1S ZeST Discovery board, can be used to drive a three-phase motor.

The board offers several sensorless strategies:

• Includes ST state-of-the-art patented technology
• Reference design
  • Low-voltage high-current inverter motor control board
• Main features
  • Input voltage (battery) from 18 V up to 48 V
  • Output current per phase up to 50 A rms continuous
  • PWM frequency from 10 kHz up to 70 kHz
  • Hardware dead time set at 250 ns
  • Hardware overcurrent protection fixed at 152 A or 236 A. A lower overcurrent value is possible through an onboard variable resistor.
  • Overvoltage detection fixed at 48 V or 96 V. A lower overvoltage value is possible through an onboard variable resistor.
• Controller board
  • This board must be coupled with a dedicated ZeST Discovery board controller through the PCI port. Refer to B-G473E-ZEST1S for further details.
