STMicroelectronics STEVAL-GLA001V1 User manual
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.

1Evaluation board objectives
1.1 What does this demoboard aim to demonstrate?
As said in the introduction, the STEVAL-GLA001V1 evaluation board allows insulated control of AC loads using
AC switches instead of relay solutions.
The board embeds a power supply to make it independent from power side.
You just have to connect mains voltage, loads and an external microcontroller.
On the smart control side, using an STM32 Nucleo board (NUCLEO-F030R8) with the available firmware allows
to easily configure a lot of parameters for specific load control.

GND_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.

“Line” and “Neutral” test points are available to measure mains voltage.
An auxiliary power supply is generated to supply the AC switch gate control: it is not regulated (fluctuates from
~12 V to ~23 V), referenced with respect to "Line" potential and can supply up to 150 mA for gate control.
“VCC_AC” and “GND_AC” test points are available to measure the power supply voltage level.
2.5.2 Power supply: secondary side
The power supply secondary side is represented by all the low power output insulated from mains voltage.
The transformer output provides 5 V regulated voltage thanks to an LDO regulator. A 3.3 V regulated voltage is
generated from the 5 V voltage thanks to a second LDO regulator.
Figure 8. STEVAL-GLA001V1 evaluation board power supply secondary side components
Up to 500 mA can be sunk from the secondary side in all, as the 5 V and 3.3 V voltages are in serial.
The J200 connector can supply another board or other external electronic functions. In this case, you must ensure
that the sum of all current on the secondary side does not exceed the output current capability.
“5VDC”, “3.3V OUT” and “GND” test points are available to measure these two low voltages.
2.5.3 VDD selector
Some of the signals (push button, mode switch and ZVS) connected to the STM32 32-bit ARM Cortex MCU or
other microcontroller input are referenced to VDD to protect the voltage input capability of any microcontroller.
UM2304
Hardware function description
UM2304 - Rev 3 page 8/46
Figure 9. STEVAL-GLA001V1 evaluation board VDD selector components
For a 3.3 V compatible microcontroller, VDD must be connected to 3.3 V by setting the SW200 jumper to the
bottom (D211 LED lights up); this is the default position.
For a 5 V compatible microcontroller, VDD must be connected to 5 V by setting the SW200 jumper to the top
(D212 LED lights up).
As VDD is connected to either 5 V or 3.3 V, the VDD current capability must always be taken into account in
matters concerning the power supply secondary side.
“VDD” and “GND” test points are available to measure VDD voltage level.
2.5.4 Push buttons
Push button signals are available on J202 (user board) and J203 (NUCLEO-F030R8 development board)
connectors. They are referenced regarding VDD and GND (refer to Section 2.5.3 VDD selector).
Figure 10. STEVAL-GLA001V1 evaluation board push button components
The push buttons are normally open and the signal is set to VDD. When a button is pressed, the signal is set to
GND. When the button is released, the signal returns to VDD.
“T1”, “T2”, “T3”, “TP+”, “TP-”, “Power Time +”, “Power Time -” and “GND” test points are available to measure
push button voltage level.
2.5.5 LEDs
LED signals are available on J202 (user board) and J203 (NUCLEO-F030R8 development board) connectors.The
microcontroller voltage level is not important as they use a transistor to be voltage compatible. LED1, LED2 and
LED3 are green, while the "Fault" LED4 is red.

Figure 11. STEVAL-GLA001V1 evaluation board LED components
If the LEDx signal is set to 0 (GND), the chosen LED is OFF; if the LEDx signal is set to 5 V, 3.3 V or VDD, the
chosen LED is illuminated.
“LED1”, “LED2”, “LED3”, “LED4” and “GND” test points are available to measure led voltage level.
2.5.6 Switch mode
The mode selector switch signal is available on J202 (user board) and J203 (NUCLEO-F030R8 development
board) connectors. It is referenced with respect to VDD and GND (refer to Section 2.5.3 VDD selector).
Figure 12. STEVAL-GLA001V1 evaluation board mode components
The switch has 3 ON positions, so there is a non-zero voltage on the MODE signal in any position. The following
table shows MODE signal voltage with respect to the switch position.
