Insulated AC switch control evaluation board for home appliances
Introduction
The
STEVAL-GLA001V1
evaluation board is designed to help you develop applications with insulated control of three AC loads
up to 1 kW (230 Vrms) using Triacs and AC switches instead of relays.
To control the STEVAL-GLA001V1, you can use a
NUCLEO-F030R8
development board which allows three AC switch control
modes for load control: continuous or pulse gate current, a timer option, and phase control. You can use also any external
microcontroller.
Once you have installed the relevant firmware (freely available at STSW-GLA001V1) on the NUCLEO-F030R8 development
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
robustness and two low voltage power supplies.
The targeted applications are residential appliances requiring insulation between microcontroller and mains voltage, such as
washing machines and dish washers, micro-wave ovens, cookers, ovens, soya-milk makers, printers, air-conditioners, fridges,
water-heaters and heaters.

Page 14: Triac Control
UM2304 Triac control Triac control A Triac or AC switch can be controlled through a DC or pulse gate command. If you apply a gate current until the Triac current exceeds I (latching current), the Triac remains ON even if the gate current is removed. The Triac turns OFF when the Triac current reaches zero, if the gate control is released. -

Page 18: Zvs Function
“Final value” entered in “td_zvs” should be the difference between the “td_zvs” delay and the inductive load delay. For example, “td_zvs” due to the STEVAL-GLA001V1 is 1000 µs, and inductive load delay is 2500 µs: the final value is “td_zvs” – “inductive load delay” = 1000 – 2500 = –1500 µs. -
Page 19: Fault Led
The firmware is able to manage ZVS circuit presence: according to the “zvs_hw” parameter value, some mode operations may or may not be available. With the STEVAL-GLA001V1, the ZVS parameter is activated by default. In case of firmware re-use with user-own design, ZVS function could be deactivated.. -

AC switch datasheet. This parameter is temperature dependent, so recalculation is required if a parameter like ambient temperature changes. STEVAL-GLA001V1 evaluation board embeds three AC switches and all gate control circuits have been calculated to ensure turn-on for ambient temperature from 0 to 60 °C. It also takes into account fluctuation on VCC_AC voltage (non-regulated auxiliary voltage referenced to mains voltage) from approximatively 13 V to 21 V. -
