The STEVAL-ISA042V2 evaluation board, developed by STMicroelectronics, is a DC/DC & AC/DC (off-line) SMPS intended for demonstrating the ease of use and effectiveness of the company’s components and control solutions. It caters to a wide range of applications that need a highly efficient AC/DC power supply solution. The board is engineered in such a way that it meets the most demanding efficient power supply designs and can be used in a variety of industrial and embedded applications, such as LED lamps, power supplies for modular systems, solar inverters, motor drive solutions, and so on.The STEVAL-ISA042V2 evaluation board is based on ST’s state-of-the-art VIPer26 Zero Current Switching (ZCS) and Resonant Mode Controllers (RMC). These components offer higher efficiency, better power density, and reduced EMI as compared to other regular solutions. VIPer and RMC are both designed to minimize electromagnetic interference while delivering maximum performance. The board also features ST\'s STM32F030 microcontroller, which, along with other on-board components, enables the board to deliver a highly efficient solution with a wide range of operating frequency.The board is capable of delivering up to 10 W of output power (at 25 °C) and operates from a wide range of input voltages, anything from 85 to 265 VAC. The board contains two main circuits, the power conversion circuit and the controller circuit.The main component of the power conversion circuit is the MOSFET. The MOSFET is used to convert a constant DC current into a pulse width modulated (PWM) output. The PWM output is generated by the Resonant Mode Controller (RMC), which provides the board with an efficient, high power transfer rate.The main component of the controller circuit is the Zero Current Switching (ZCS) VIPer controller. This controller utilizes an advanced soft-switching control technique to achieve zero current switching. This means that no current is drawn during the transition periods of the switching signals, allowing for a more efficient power conversion.The user can also control the board\'s parameters with the onboard STM32F030 microcontroller, making the STEVAL-ISA042V2 evaluation board an easy to use and highly interactive learning platform. Some of the parameters that can be controlled are input voltage, frequency, output voltage, and current limit. The board also features a voltage-mode driver control, which allows users to adjust the switching frequency and dead time values.Overall, the STEVAL-ISA042V2 evaluation board is an excellent choice for any applications that need an efficient AC/DC power supply solution. It is designed to provide users with an easy-to-use platform that allows them to quickly evaluate and efficiently develop their AC/DC power conversion solutions.
