　　BLDC ceiling fan controller based on STM32 and SLLIMM-nano

　　The STEVAL-IHM038V1 system evaluation board implements a BLDC/PMSM fan controller board which is based on the SLLIMM™-nano (small low-loss intelligent molded module) STGIPN3H60 and STM32F100C6T6B microcontroller. The STEVAL-IHM038V1 incorporates a complete inverter stage and a control stage to drive a 3-phase BLDC fan motor with a power range of 30-35 W with FOC (field oriented control) sensorless mode for the ceiling fan applications. For power factor correction, a passive PFC stage is implemented to achieve a power factor up to 0.90, which is the minimum recommended for ceiling fan applications, particularly for the Indian market. To set the speed by remote control, an on-board IR demodulator is available.

　　The inverter stage is implemented using the intelligent power module SLLIMM™-nano STGIPN3H60 which embeds 600 V IGBTs with gate drivers, op amp for current sensing and a comparator in a single NDIP-26L package, resulting in a reliable and compact system design.

　　The control part includes field oriented control with sensorless control algorithm, fault detection and speed setting via remote control (IR receiver), all handled by the STM32F100C6T6B microcontroller from ST’s ARM®Cortex™-M3 core-based low density STM32™ MCU family.
