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..
Table 3. Modes and gate controls available vs zvs circuit implementation lists all load modes and gate control
types available regarding ZVS circuit implementation.

All parameters (range, default value, unit, etc.) used to configure the ZVS delay are described in Section 3.6 User
interface . For more details regarding the hardware components used for this function, refer to
Section 2.5 Hardware function description .
3.5 Fault LED
The red fault LED lights ON to indicate an error. Your can determine the fault type through the user interface (for
more details, refer to firmware user manual). For more details regarding the hardware components used for this
function, refer to
Section 2.5 Hardware function description .
3.6 User interface
The user-friendly interface is designed to let you read and write parameters easily. This interface consists of many
commands (described in a menu) available through a terminal emulator such as HyperTerminal or TeraTerm. The
list of commands is shown below.
