Low cost 12VDC to 120/220VAC Inverter

2009-07-08T19:25:00.004+03:00

This inverter will sufficiently power any of your 115VAC (or 220VAC)small appliances। T1 choice of amperage is yours to make, but if you can salvage a heavy-duty unit from somewhere, use it. The least expensive method to get a larger transformer would be to remove the old 2000v primary and then re-wind an old microwave transformer. Most of these transformers are rated 1KW or better.

PA300 power amplifier (Elektor 11/1995)

2009-07-06T01:28:00.013+03:00

Design by A. Riedl Taken by themselves, the properties of the PA300 amplifier are not revolutionary. But taken in combination, they show something special: a robust 300 watt hi-fi power amplifier that is not too difficult to build.There are several starting points to the design of a power amplifier: pure hi-fi without any compromise; simplicity and reliability; high output power. The design of

A ideal solution for the make a good, low cost power amplifier. Itï¿½s a ideal solution for the creation a system of home cinema. The preamplifier and the driver support in a operational amplifier [IC1]. The voltage fall in resistors R5 and TR2/R6, drive the output FET’s gates and is proportional with the input signal level. Transistors Q1-2 function as voltage stabilizers in the supply lines,

170 Watt Class D Audio Power Amplifier with LM4651 and LM4652

2009-06-24T11:38:00.010+03:00

DescriptionThe IC combination of the LM4651 driver and the LM4652 power MOSFET provides a high efficiency, Class D Amplifier solutionThis circuit is ideal for car booster amplifier, active speaker/subwofer, home theater, or PC’s multimedia sound system. The maximum efficiency 85% is obtained at 125W power output condition। The total harmonics distortion is 10% at full power output of 170W। For

2 x 25 W class-D power amplifier with TDA8922.

2009-06-24T02:26:00.013+03:00

General descriptionShowThe TDA8922 is a high efficiency class-D audio power amplifier with very low dissipation. The typical output power is 2 X 25 W.The device is available in the HSOP24 power package with a small internal heatsink and in the DBS23P through-hole power package। Depending on the supply voltage and load conditions, a very small or even no external heatsink is required.

2009-06-06T13:46:00.004+03:00

DescriptionThis simple circuit mixes two or more channels into one channel (eg. stereo into mono). The circuit can mix as many or as few channels as you like and consumes very little power. The mixer is shown with two inputs, but you can add as many as you want by just duplicating the "sections" which are clearly visible on the schematic.Partlist2x 10K Pot (R1, R3) 2x 100K 1/4 W Resistor (R2, R4)
