It is used to evaluate a range of switching power supplies, enabling users to test and measure power levels, stability, and so on. It is designed for use in a variety of applications, including industrial, consumer, gaming, medical and automotive.

The STEVAL-ISV013V1 is an open-loop SMPS board that can be used with a varying range of input voltages, including 50 V/DC to 400 V/DC. This page will discuss the working principle of the evaluation board and the applications it is suitable for.

Working Principle

At the heart of the STEVAL-ISV013V1 is a synchronous MOSFET boost converter. It uses a controller IC, which is powered by an external DC power source. The controller IC is responsible for regulating the output voltage of the boost converter. At normal operation, the controller IC will regulate the MOSFET\'s switching duty cycle based on the applied input voltage. There is also protection circuitry on the board that protects the MOSFET from overvoltage and overtemperature conditions.

The output of the boost converter is fed to a synchronous full bridge rectifier. This rectifier rectifies the output AC voltage to DC for use in the application. Since the output of the bridge rectifier is unregulated, it is then fed to an LC-filter to ensure a clean and filtered output. The output of the LC-filter then goes to the application load.

In addition to the SMPS, the board also includes an isolated gate driver for the MOSFET and a current sense circuit to measure the output current of the bridge rectifier. The board also includes a Microchip MCU for monitoring the input voltage, output voltage, and output current. The MCU can also be used to provide additional protection features.
