Abstract
An integrated script control unit (ISCU) is invented to work as the digital controller in power electronics educations. The ISCU mainly consists of two parts, a control board and computer software. The computer software enables college students to write specific scripts, which can be compiled and saved on the control board, to design the control flow and algorithms. The processor on the board will realize the algorithms that are designed by the user. All of the variables can be monitored by the computer software, which is helpful to find the bugs in the algorithms. ISCU can help the under-graduate students to design converters even if they are unfamiliar with the programming languages and developing environment. Users can write and validate algorithms for converters quickly without writing any tedious codes (such as initialization, dealing with the interrupts) for specific processors with ISCU. The college students who lack the necessary skills to program the processor, can benefit when they are studying the power electronic techniques. Importantly, the ISCU is considered to be free for everyone. The details and the principles of ISCU are introduced, and a bi-directional DC-DC converter is built based on ISCU to validate the proposed characteristics.
Highlights
In recent years, power electronic converters have gained much attention and are widely used in many industrial and commercial fields, such as motor drives, power sources, and wind power generation [1,2,3,4,5,6,7,8]

Literature [9] studied the inherent relationship between two pulse width modulation methods for multilevel converters and carried out an experiment based on TMS320F2812
Summary
Power electronic converters have gained much attention and are widely used in many industrial and commercial fields, such as motor drives, power sources, and wind power generation [1,2,3,4,5,6,7,8]. The experimental setup was based on the 32-bit floating point DSP TI TMS320F28335 The digital processors such as TMS320F2812 and TMS320F28335, are powerful enough to carry out the control algorithm in power electronic converters. It is initialize the chip and control the peripherals. Because they areAs not familiar the digital processors, areanot able to finish the of the power electronics They cannot try or design their own control algorithm for the converter experiments on their own. ISCU provides a script system, which is simple and easy to learn for the the to design the algorithm for a converter without writing any code for the processor.
