Evaluation and Demonstration Boards and Kits

The DC855A-A is a versatile evaluation and demonstration board for power supply applications. Developed by the Power Electronics Research Laboratory (PERL) at Arizona State University, it is designed to emulate a variety of power system simulation and control algorithms. In addition, the DC855A-A can also be used as part of a power conversion system for energy storage, power control systems and distributed energy resources.

The DC855A-A features a variety of features for power supply systems. The board includes an adjustable DC power source, two programmable digital output channels for controlling switching action, and two analog input channels for monitoring input signals. It also incorporates a high frequency square-wave oscillator for providing a precise switching frequency. This enables the evaluation board to replicate critical voltage, current, and frequency signals.

For use in simulation and control algorithms, the DC855A-A includes a real-time controller to allow for fast and accurate system responses. The controller adjusts the output voltage, current, frequency, and other parameters of the power system as needed. The controller also includes a digital input/output interface for communication with a computer for real time analysis and control of the system.

The DC855A-A board also includes various safety functions to protect the board from overloads. Its overvoltage protection mechanism switches off the power to the board when the voltage exceeds a defined level. This allows the board to operate at a safe voltage and prevents hazardous power surges. The board also features a current limit protection, which cuts off the power supply when the current exceeds a specified limit.

The DC855A-A incorporates an onboard analog-to-digital converter for the analog input channels. This enables the board to capture and store signals from external sources, such as sensors or dc voltage measurements, for use in the simulations and control algorithms. The board also includes a digital communication interface for data exchange with a computer for further analysis and processing.

The DC855A-A evaluation and demonstration board can be used for a wide range of applications. It can be used for research and development in novel power systems for distributed energy resource applications, or for simulating and controlling complex power systems. The board can also be tested in prototype products for changing power systems in automobiles, hybrid vehicle systems, and smart grids. This makes it a versatile and powerful tool for power electronics researchers and engineers.
