Computing: Free Pascal Programming

Properties of an ideal transformer.

Download Transformator desktop application (Windows 64bit)

Download Transformator source code (Lazarus/Free Pascal)

Description: Simple electronics application concerning ideal transformers. The application gives students the possibility to study the following transformer properties:

• Voltage transformation: Increase of the secondary voltage when increasing the number of secondary coil turns.
• Current transormation: Decrease of the primary current when increasing the number of primary coil turns.
• Impedance transmission: Variation of the secondary impedance when changing the number of primary/secondary coil turns.

The student has to enter the starting data for the ideal transformer and then can use a trackbar to gradually increase the number of primary resp. secondary coil turns. The studied parameter (secondary voltage, primary current, secondary impedance) is changed accordingly. Its values are also displayed on a simple graph (as a function of the number of turns).

Free Pascal features: Radiobuttons. Trackbars. Hiding/showing controls as needed. Changing label captions during runtime.
