Description<\/span><\/strong><\/h2>\n

The module is created for the third year specialized power electronic laboratory. A set of the experiment consit of 2 PCB board.<\/p>\n

The PWM Generator Board generates the required signal to switch the MOSFET. The potentiometer allows the change of duty cycle for the PWM. This board also equipt with a 7-segment LED TM1637 display to show the duty cycle.<\/p>\n

The Converter Board provides the buck, boost, or buck-boost converters connections. This is achieved by vary the location of the MOSFET, inductor, and diode. The location of the capacitor, load, and voltage source remain intact.<\/p>\n
