Audio : Power Amplifier Circuit with 2N3055
Power Amplifier Circuit with 2n3055. Simple and low cost power amplifier. The optimal accumulation voltage is about 50V, but this amp assignment from 30 to 60V. The acute ascribe voltage is about 0.8 – 1V. As you can see, in this architecture the apparatus accept a big tolerance, so you can body it about of the components, which you acquisition at home. The and transistors can be any NPN blazon ability transistor, but do not use Darlington types. The achievement ability is about 60W.

Power inverter : 12VDC to 220VAC With Cmos 4047
This converter has a central component, the CMOS 4047, and converts a 12V DC voltage to 220V AC voltage. 4047 is utilised as a astable multivibrator. At pin 10 and 11 we find a rectangular symmetrically signal which is amplified by tow Darlington transistors T1 and T2 and finally reaches the secondary coil of a transformer network (2 x 10V/60VA). Primary coil terminals voltage is 220 alternative voltage. Read the rest of this entry »
