1、June 2011Doc ID 15870 Rev 41/48 UM0723 User manual 1 kW three-phase motor control demonstration board featuring L6390 drivers and STGP10NC60KD IGBT 1 Introduction This document describes the 1 kW three-phase motor control demonstration board featuring the L6390 high and low-side drivers and the STGP
2、10NC60KD IGBT. The demonstration board is an AC/DC inverter that generates a three-phase waveform for driving three or two- phase motors such as induction motors or PMSM motors up to 1000 W with or without sensors. The main device presented in this user manual is a universal, fully evaluated, and po
3、pulated design consisting of a three-phase inverter bridge based on the 600 V STMicroelectronics IGBT STGP10NC60KD in a TO-220 package mounted on a heatsink, and the L6390 high- voltage high-side and low-side driver featuring an integrated comparator for hardware protection features such as overcurr
4、ent and overtemperature. The driver also integrates an operational amplifier suitable for advanced current sensing. Thanks to this advanced characteristic, the system has been specifically designed to achieve an accurate and fast conditioning of the current feedback, therefore matching the typical r
5、equirements in field oriented control (FOC). The board has been designed to be compatible with single-phase mains, supplying from 90 VAC to 285 VAC or from 125 VDC to 400 VDC for DC voltage. With reconfiguration of the input sourcing, the board is suitable also for low-voltage DC applications up to
6、35 VDC. This document is associated with the release of the STEVAL-IHM023V2 demonstration board (see Figure 1 below).
