Working Principle of The PTK25-D48-D15

The PTK25-D48-D15 converter operates on the principle of buck-boost topology, using an insulated gate bipolar transistor (IGBT) along with a diode bridge rectifier to produce a switching power supply from a battery or other DC powersource. The converter takes in the DC input voltage, converts it to AC, and then back to DC with a higher or lower voltage than the input voltage. This is done using a switching transistor and a diode bridge rectifier that alternately close and open, allowing and blocking current flow. This process creates an alternating current that is rectified to create the desired DC output voltage.

The PTK25-D48-D15 converter also features an onboard microcontroller that allows it to be programmable, offering various features such as automatic temperature control, under voltage protection and over temperature protection. The microcontroller also allows it to accept pulse-width modulated (PWM) signals for controlling the output voltage and current.
