  • The STEVAL-IHT005V2 is designed as a complete solution proposal for home appliance applications based on STMicroelectronics™ components. Special emphasis is placed on demonstration of a robust full 3.3 V solution, based on 4 kV level in class A during an IEC-61000-4-4 (burst) test. The board also allows designers to evaluate the feasibility of AC switch control with a 3.3 V supply. Gate currents can be measured and compared to the information given in application note AN2986. STEVAL-IHT005V2 is based on the recently-introduced 48-pin, 32-bit STM32F100C4T6B MCU running at 24 MHz (RC user-trimmable internal RC clock), featuring 16 kBytes of Flash memory, 12-bit A/D converter, 5 timers, communication interfaces, and 4 kBytes of SRAM. The power supply circuitry is based on the VIPer16L, an offline converter with an 800 V avalanche-rugged power section, operating at 60 kHz. The power supply provides negative 6 V in buck-boost topology. The STEVAL-IHT005V2 can control 2 high power loads up to 2830 W thanks to the T1635H, a 16 A, 600 V high temperature Triac and up to 2050 W using the ACST1635-8FP, a 16 A, 800 V high temperature overvoltage-protected ACST device. The high power load control is based on phase-angle control. To limit inrush current and possible current peaks, the board features a soft-start routine and a smooth power change function for the high power loads. The STEVAL-IHT005V2 can also control 4 low power loads up to 100 W thanks to 3 ACS108-8S, 0.8 A, 800 V overvoltage-protected ACS devices and a Z0109, 1 A standard 4 quadrant 600 V Triac.
