STMicroelectronics STEVAL-IHT005V2 演示板

STMicroelectronics STEVAL-IHT005V2 演示板带有完全 3.3 V ACS/Triac 控制，使用 STM32F100，基于 STMicroelectronics™ 元器件为家电应用提供了完整的解决方案。该板使设计人员能通过一个 3.3V 电源来评估交流开关控制的可行性。重点放在对强大的全 3.3V 解决方案的验证，基于 IEC- 61000-4-4（浪涌）试验中的 class A 4 kV 。

STMicroelectronics STEVAL-IHT005V2 Demonstration Board can control two high power loads up to 2830W thanks to the T1635H, which is a 16A, 600V high-temperature triac, and up to 2050W using the ACST1635-8FP, which is a 16A, 800V 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 four low-power loads up to 100W thanks to three ACS108-8S, which are 0.8A, 800V overvoltage-protected ACS devices, and a Z0109, 1A standard four-quadrant 600V triac.
