STMicroelectronics STEVAL-IHT005V2 Demonstrationsplatine
Die STEVAL-IHT005V2 Demonstrationsplatine von STMicroelectronics mit voller 3,3V ACS/Triac-Kontrolle unter Verwendung von STM32F100 bietet auf Basis von STMicroelectronics™-Komponenten eine Komplettlösung für Haushaltsgeräte. Die Platine ermöglicht Designern, die Machbarkeit einer AC-Schaltkontrolle mit einer 3,3V-Versorgung zu bewerten. Besonderes Augenmerk liegt auf der Demonstration einer robusten kompletten 3,3V-Lösung, die auf einer 4kV-Ebene der Klasse A während einer IEC- 61000-4-4-Prüfung (Bersten) basiert.
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.
