ST STEVAL－IHM021V2 100W马达矢量控制方案

ST公司的STEVAL-IHM021V2是采用L6390和STD5N52U的3相马达控制板,用于永磁同步马达(PMSM) 矢量控制,正常输出功率高达100W,和110VAC与230VAC火线电压兼容,主要用在冰箱压缩机和洗碗机.本文介绍了L6390主要特性, 方框图和应用框图,以及采用L6390和STD5N52U的100W三相马达矢量控制板STEVAL-IHM021V2主要特性,方框图,电路图和材料清单.

The L6390 is a high-voltage device manufactured with the BCD “OFF-LINE” technology. It is a single chip half-bridge gate driver for N-channel power MOSFET or IGBT.

The high side (floating) section is designed to stand a voltage rail up to 600 V. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing microcontroller/DSP.

The IC embeds an operational amplifier suitable for advanced current sensing in applications such as field oriented motor control.

An integrated comparator is available for protections against overcurrent, overtemperature, etc.

L6390主要特性:

■ High voltage rail up to 600 V

■ dV/dt immunity ± 50 V/nsec in full temperature range

■ Driver current capability:

– 290 mA source,

– 430 mA sink

■ Switching times 75/35 nsec rise/fall with 1 nF load

■ 3.3 V, 5 V TTL/CMOS inputs with hysteresis

■ Integrated bootstrap diode
