E246T
DC Dynamic Braking (Timed & Monitored)

Carlo DeLuca, PE, MBA

This course will develop a circuit design intended to perform a specific function. The task of the circuit, commonly known as “dynamic braking,” is to provide electrical braking of a DC motor. Particular attention is given to specifying circuit components and defining energy and time constraints when applying braking concepts. Parameters of the task are established relating to function, application and component requirements.

Initially, a circuit is described using an energy storage device, namely a capacitor. Once the circuit is verified, determination of the components and their values is accomplished. Although the circuit is shown to satisfy the task, mathematical analysis, involving integration, reveals that the size of the storage device is not feasible in this application. A second circuit is devised employing an alternate approach. This leads to an analysis of the relationship of time to capacitor discharge. Again, determination of components and their values is made, using circuit analysis and mathematics. This circuit provides acceptable performance, function and component feasibility.

In the process of designing both circuits, a more objective lesson is realized. Guidelines are presented that illustrate effective engineering approaches in basic circuit design. The importance of a proper technique in defining the task and parameters becomes evident. The approach to conduct logical mathematical analysis, even on a simple approach, is clearly illustrated.

This course includes a multiple choice quiz at the end, which is designed to enhance the understanding of the course materials.

User's Guide to Timed & Monitored Online Courses:

For Timed & Monitored (T&M) online courses, you need to log into your account to view the course content. You must complete the required study time (min. 50 minutes for each PDH) before you can submit your quiz answers and obtain your certificate of completion. However, you may print out the quiz questions anytime after purchase.

You do not need to complete the T&M course in one sitting. You may view the course content from office or home using different devices with Internet connection. Our website will keep track of your total time spent. If necessary, you may print the course content for ease of reading while you are online. You may also preview the content of E246T by viewing the content of E246 since they are identical.

For T&M courses, You need to actively view course content online - at least click your mouse once in a while. The on-screen tracking clock may stop due to inactivity at your end. If that happens, you may resume your clock by pressing F5 key on your keyboard or by refreshing your screen. Thank you for your cooperation.

Note: This course requires users to pay first before viewing the course content.
