Amplifier power supply using High Current Transformer

Circuit Description    
    Friends ever meet a problem power supply Circuit give current not enough. I has way this out give friends try apply. Follow this circuit High Current transformer parallel circuit make you have Current tall go up very. The transformer that have many the coil , we can bring to do high Current power supply circuit well. By if the all coil has Voltage be equal. It is can bring parallel can follow this circuit is coil lead that has Voltage 24V and have Current about 1A come to parallel prevent all 2 the group have current altogether each 2A groups by have voltage at 24V be the same. This circuit then can become Dual power supply at 34V positive and -34V Negative and Ground. This circuit uses to are amplifier power supply get good. Suppose will give the electric power about 50watt. For the diode use 3A 100V sizes and use. The Stancor for filter noise signal the all well. This circuit may help to give testimony have the idea in applying work other , get please sir.

200W Hybrid Audio Amplifier Circuit

200W Hybrid Audio Amplifier Circuit - c onnecting two TDA2030 thru cheap power transistors we can create a amplifier wich can deliver a higher power. With the components value from the schematic the total amplifier gain is 32 dB. The speaker can be 2 ohm instead of 4 ohm if we use the TIP transistors. TDA 2030 is produced by SGS Ates and is a complete audio amplifier. AB class of the final amplifier cand deliver up to 14W on 4 ohm at a +-14V power supply. With a proper designed power supply this audio amplifier can output 200W. Active components: IC1, Ic2 TDA 2030 T1, T3 = BD 250, TIP 36 T2,T4 = BD 249, TIP 35 D1 … D4 = 1N4001 200W Hybrid Audio Amplifier Circuit

2 x 15 W stereo Bridge Tied Load (BTL) audio amplifier

General description: The TDA8946J is a dual-channel audio power amplifier with an output power of 2 × 15 W at an 8 Ω load and a 18 V supply. The circuit contains two Bridge Tied Load (BTL) amplifiers with an all-NPN output stage and standby/mute logic. The TDA8946J comes in a 17-pin DIL-bent-SIL (DBS) power package. The TDA8946J is printed-circuit board (PCB) compatible with all other types in the TDA894x family. One PCB footprint accommodates both the mono and the stereo products. Features: Few external components Fixed gain Standby and mute mode No on/off switching plops Low standby current High supply voltage ripple rejection Outputs short-circuit protected to ground, supply and across the load Thermally protected Printed-circuit board compatible Circuit Diagram: Circuit Diagram for 2 x 15 W stereo Bridge Tied Load (BTL) audio amplifier PCB layout: PCB layout TDA8946 Datasheet for TDA8946J:   Download
