Evaluation boards are among the most powerful tools available to measure a wide range of parameters, from basic measurements to complex theoretical models. Whether it is for power factor correction or for power conversion efficiency, an evaluation board will often provide the necessary data needed to accurately test a system before a full-fledged implementation is made. The STEVAL-ISA009V1 is an evaluation board used in DC/DC & AC/DC (Off-Line)SMPS applications.

The STEVAL-ISA009V1 evaluation board consists of a 750W buck converter power stage evaluation kit with active transient response. This board can be used to study the main features of a power stage, in addition to analyzing the efficiency of various circuits, such as power factor correction, overload protections and active transient response. The evaluation board is also suitable for researching the dynamics of load sharing. It also provides the user with the ability to measure the input and output of the device, as well as the transient voltage, current and power.

In order to evaluate faults or explore the limits of operation, the STEVAL-ISA009V1 evaluation board provides a short-circuit protected device status and a continuous voltage control. Furthermore, the evaluation board has an embedded temperature sensor for precise thermal management. It also includes an LCD display for visualization of all data acquired during tests.

To make this powerful evaluation board really useful in the applications mentioned above, its working principle must be understood. The STEVAL-ISA009V1 evaluation board works on the basis of pulse width modulation (PWM). The PWM input is fed directly to the device, typically to a wafer switch. This wafer switch acts like a single switch, which, depending on the voltage level received, produces semiconductor pulses that are then connected and disconnected to the primary side of the buck converter.

When these pulses reach the primary side of the converter, they reach the transformer which produces the voltage on the secondary side needed to control the device. Consequently, by controlling the width of the pulses that reach the primary converter, the voltage on the secondary side is controlled. The current flowing from the device is then regulated and determined by the output voltage and the number of turns in the transformer.

The STEVAL-ISA009V1 evaluation board also contains a temperature protection sub-system, which ensures that the device does not overheat and damage itself. It provides various protection features to avoid damage from overloading or shorting the device. This sub-system uses an integrated temperature probe to monitor the temperature and take action as required.

The STEVAL-ISA009V1 evaluation board is also capable of providing fault diagnosis. It can detect overcurrent protection, which helps to ensure the safety of the connected device, and it can also detect short-circuit protection. Additionally, it can detect and diagnose other faults, such as pulse-skipping behavior or temperature protection.

The STEVAL-ISA009V1 evaluation board is a powerful tool for DC/DC& AC/DC (Off-Line) SMPS applications. It is capable of providing precise measurements and highly-regulated voltage control, while offering fault diagnosis and temperature protection. Its wide range of features allows users to study a variety of parameters, from basic measurements to complex theoretical models. This board is an invaluable tool for anyone looking to test a system before full-scale implementation.
