STMicroelectronics VIPer16LN | Demoboard STEVAL-IHM038V1

Description

This document describes the STEVAL-IHM038V1 evaluation board, a completeBLDC/PMSM 3-phase motor drive suitable for mains supplied motor control systems up to50 W and particularly suitable for fan controllers. The board is based on SLLIMM™-nano(small low-loss intelligent molded module) STGIPN3H60 and MicrocontrollerSTM32F100C6T6. The evaluation board enables 3-phase permanent magnet motor fieldoriented control (FOC) in sensor-less mode. For power factor correction, a passive PFCstage is implemented to achieve a power factor of up to 0.90 (in line with many norms suchas the ones prevalent for ceiling fans in India). An on-board IR demodulator allows speedadjustment using a remote control.The inverter stage is implemented using the Intelligent power module SLLIMM™-nanoSTGIPN3H60, which embeds 600 V IGBTs with gate drivers, op-amp for current sense anda comparator in a single NDIP-26L package for reliable and compact system design.The control part, including field oriented control with sensor-less control algorithm, faultdetection and speed setting via on-board switches and remote control (IR receiver) are allhandled by the STM32F100C6T6B microcontroller of the STMicroelectronics™ ARM®Cortex™-M3 core-based low density STM32™ MCU family.

Features

The STEVAL-IHM038V1 has the following features:

• maximum input voltage: 265 V AC or 375 V DC
• minimum input voltage: 90 V AC or 128 V DC
• maximum output power for applied motor: up to 50 W (continuous)
• +15 V auxiliary power supply based on VIPer16LN in a non-isolated buck configuration
• compact design using SLLIMM™-nano STGIPN3H60 featuring 600 V IGBTs with gatedrivers, op-amp for current sense and comparator
• passive PFC circuit for power factor correction: Passive PFC is a standard Valley filldesign where the two power supply capacitors are charged in series and discharged inparallel using three diodes to reduce the ripple current. This in turn improves the powerfactor as compared to a single capacitor configuration.
