STEVAL-IHM029V1 2000 W universal motor control demonstration board based on the STM8S103F2 MCU and T1235H Triac Data brief Features ■ Input voltage range: 90-265 VAC, 50/60 Hz ■ 12 VDC / 5 VDC auxiliary power supply based on the VIPer16L in buck converter topology ■ Total power consumption below 300 mW in standby mode ■ Maximum output power: 2000 W ■ 20-pin, 8-bit STM8S103F2 MCU as main controller ■ Employs zero-voltage switching (ZVS) to synchronize MCU events with the voltage mains ■ Motor driven by T1235H high-temperature Triac in phase-angle control ■ 5 power levels and standby mode selectable by potentiometer ■ 5 LEDs to display the power level of the board ■ “RUN” LED to indicate the board is functioning ■ Standard in-circuit programming connector ■ IEC 61000-4-4 pre-compliance test passed (burst up to 8 kV) ■ IEC 61000-4-5 pre-compliance test passed (surge up to 2 kV) ■ RoHS compliant Description The STEVAL-IHM029V1 is a low-cost universal motor control demonstration board designed for the home appliance market, with particular focus on vacuum cleaners, food processors and power tools. STEVAL-IHM029V1 The power supply circuitry is based on the VIPer16L, an off-line converter with an 800 V avalanche-rugged power section, operating at 60 kHz. The STEVAL-IHM029V1 can control any universal motor up to 2000 W, thanks to the T1235H, a 12 A 600 V high temperature Triac. The motor control is based on phase-angle. In order to limit the in-rush current and possible current peaks, the demonstration board features a soft-start routine and a smooth power change function. The board passed the pre-compliance tests for EMC directives IEC 61000-4-4 (burst up to 8 kV) and IEC 61000-4-5 (surge up to 2 kV). In standby mode, the STEVAL-IHM029V1 has an overall standby power consumption below 300 mW. This system features the 20-pin, 8-bit STM8S103F2 microcontroller running at 16 MHz (RC user-trimmable internal RC clock), featuring 4 KB of Flash memory, a 10-bit A/D converter, 8/16 bit timers, communication interfaces and 640 bytes E2PROM.
