LM317T Voltage Regulator with Pass Transistor

Got a CRT TV with a power supply failure that is too complicated or expensive to repair? Get one of these one-size-fits-all Universal TV PSUs. They provide the necessary voltages to power up all of the TV's internal circuits, just disable the original PSU, wire the replacement in and find some place inside the set to hold the board in place. Your TV will come back to life! In this video I show you how I got a 21" Panasonic that survived last year's 8.8 earthquake back to life with one of these universal supplies. The switching transformer was cracked making repair a complicated and expensive affair. Fitting the universal PSU to replace the main B+ supply got it working and saved me quite a bit of money and headaches! I got this particular model locally from www.cm2.cl Here's the very same one from an online distributor tinyurl.com

www.microchip.com Walk through the basics of a charge pump circuit. Each components significance is highlighted using a series of slides that show both the schematic and output waveforms. Next, a pulse train is applied to the circuit to create a voltage doubler. Intelligence is later incorporated using a comparator peripheral on a PIC Microcontroller to regulate output voltage. All equations required to build the circuit are discussed as well as derivations and importance. Finally, using the same components, a voltage inverter is created to show some alternate configurations.
