30V Regulated Power Supply Circuit
I would like to share with you my project dual power supply. The project was created on paper so you do not have full documentation to the tiles that have been made in a very simple way using a special pen in addition to platelet stabilizer. These tiles bought from documentation in an electronics store. Brief characteristics of the power supply:
-AC has two independent branches with galvanic isolation -Output power supply can operate as a series or parallel
-Additional output 5V and 3A current-limited -System has thermal protection which the heat sink temperature of 95 ° C disconnects the output from the load -Threshold load shedding when the voltage drop at the output will be below the limit set for the help switch “CUT OFF” 0.7V, 3V and 12V -OVERLOAD Overload Protection that shuts off the stabilizer in the power supply, the reset button to return to work the stabilizer
The power supply voltage used the four measures based on ICL7107 converter and a temperature gauge on the system ATMEGA8 PLED display that I bought on Allegro. Each meter has its own voltage DC / DC converters in order to isolate the mass of the system. For cooling, the power supply used a very quiet and efficient fan size 12cm x 12cm company NMB. The transformer has the power of 600W and provides 2 x 24V voltage.

dsPIC30F2020 LED Psychedelic TC4427A MCP608 MCP6022 MCP6S26
The project requirements are related to technologies adopted: high power LEDs need to be driven with a constant current; digital filters need a fast DSP engine, to be implemented, and an A/D converter is required to transform an audio signal in a numerical representation. Control data communications between central processing unit and external analog components require to have an SPI on board and, last but not least, the capability to link the system with a PC could be very useful for firmware debugging and for tuning some parameters in real time without needing expensive developing tools.
The dsPIC30F2020 perfect matches all these needs having a very powerful 4 channels independent PWM generator with current fail detection suitable for drive 3 LEDs in a buck booster configuration through two MOSFET drivers TC4427A a built-in 2Msps A/D converter and a DSP core featuring 17×17 bit multiplications for filters implementation; an SPI hardware for in-system communications; an RS232 compatible block useful for communications with an external PC.
