DCAC Inverter (EN)
A Training Project for a 12V DC to 230V AC inverter
This project is an example for action orientated training (in German: Handlungsorientiertes Training). The program was developed 2015/2016 by me, Thomas Hitzner, and Michael K. Ford. We implemented it for the unit "Power Electronics" at the Yanbu College of Applied Technology. Feel free to download following example documents (use "save target as ..."):
The training is
divided into two dimensions:
Dimension 1: The project targets three (3) different objectives:
Improve the trainees technical knowledge about DC-AC inverters; this content is the same as for the course Power Electronics.
- Improve trainees knowledge and understanding of how to manage projects. Trainees are encouraged to do this project correctly by following the project management rules.
- Improve the English skills of the trainees.
Dimension 2: This project is divided into 5 phases- just like with a timeline.
These phases are designed to be action-oriented training. The trainer will act
as a moderator. Activities will be done mostly by the trainees. Every phase has
exercises for technical knowledge, project management knowledge and English
Phase 1: Understanding the project
The trainer defines and explains the project.
He divides the class into working groups, so that trainees will have an
orientation class to understand about the timelines. The trainer will then
discuss with the trainees about the importance of DC-AC inverters. Later on
trainees will have to find examples of where to use power inverters in their
own life. The trainer will explain with examples how SMART terminology will be
used in this project.
Phase 2: Collecting Information about the project
Groups will be selected and remain the same
throughout the project. Trainees will be working in groups of two or three. It
is important to know that trainees must educate and inform themselves. This can
be completed through use of journals, textbooks, internet and communication
with other training organizations, etc. After that, trainees will have to
select the information which is best to create the product. Assistance by the
trainer will be given only if needed.
Phase 3: Planning and designing of the product
The groups must now develop a work plan. The
trainer can present an example solution at the end of the phase for groups who
have weak results.
Phase 4: Project implementation
Implementation means performing and
completing the activities described in the work plan. It requires the
coordination of many different activities. The product, the DC-AC inverter, is
only one part of the project. Trainees will also have to deliver documentation
and test boards or prototypes, week by week.
Phase 5: Evaluation of the project
The groups present their work results. Other
groups will evaluate the result. Mistakes should be analyzed and alternatives
developed. "Learning from mistakes" is an important idea to
understand and practice in this action-oriented project!
