ST公司的STEVAL-GLA001V1是采用可控硅(Triac)和交流(AC)开关来替代继电器的家用电器开发平台,能绝缘控制三个高达1kW的AC负载,具有宽输入电压范围,低待机损耗,IEC61000-4-4鲁棒和两个低压电源.主要用在微控制器和主电压需要隔离的家用电器如洗衣机,洗碗机,微波炉,灶具,烤箱,豆浆机,打印机,空调,冰箱和热水器和加热器.本文介绍了评估板STEVAL-GLA001V1主要特性,框图,电路图,材料清单以及PCB顶层丝印图.

The STEVAL-GLA001V1 evaluation board is designed to help you develop applications with insulated control of three AC loadsup to 1 kW (230 Vrms) using Triacs and AC switches instead of relays.

To control the STEVAL-GLA001V1 evaluation board, you can use a NUCLEO-F030R8 development board which allows threeAC switch control modes for load control: continuous or pulse gate current, a timer option, and phase control.

Once you have installed the relevant firmware (available free on the STEVAL-GLA001V1 web page) on the NUCLEO-F030R8development board, you can start adjusting the main parameters through a common serial interface like HyperTerminal.

The STEVAL-GLA001V1 evaluation board features a wide input voltage range, low standby power losses, IEC61000-4-4 robustnessand two low voltage power supplies.The targeted applications are residential appliances requiring insulation between microcontroller and mains voltage, such aswashing machines and dish washers, micro-wave ovens, cookers, ovens, soya-milk makers, printers, air-conditioners, fridges,water-heaters and heaters.

评估板STEVAL-GLA001V1主要特性:

The STEVAL-GLA001V1 evaluation board features the following main components:
• AC switches (X101, X102 and X103)
• A flyback power converter providing:
– VCC_AC: non regulated output and referenced to mains voltage (VCC_AC positive regardingGND_AC).
◦ used to control the three AC switches.
◦maximum output current: 150 mA
– 5VDC: 5 V positive output, referenced to GND, insulated regarding mains voltage.
◦ supplies the LEDs and all other electronic parts if VDD selector is set to 5V position
◦maximum output current: 500 mA for all the secondary side (5 V, 3.3 V and VDD mixed)
– 3.3VDC: 3.3 V positive output, referenced to GND, insulated regarding mains voltage.
◦ supplies all other electronic parts if VDD selector is set to 3.3 V position.
◦maximum output current: 500 mA for all the secondary side (5 V, 3.3 V and VDD mixed)
– VDD: used to select whether the external microcontroller is supplied with 5 V or 3.3 V (default).
