I too once I’ve tried a circuit I do a single channel the bridge tda2030 output transistor was powered by this application plus two half bridges connected in parallel to power two times removed amplifier supply voltage symmetrical + – 22 volts without an error as long as the work is certain circuit further on google search box “TDA2030A bridge ‘, then in the pictures if you search you can find a lot of similar applications on the same circuit two single plaque 400Watt amphitheater If you have two-channel stereo and transistors integrated isolators use when mounting the cooler

The peak-to-peak voltage Vpp, with a load resistance at the 4 Ω pending an output of 200 watts, is 80 volts. If we add another additional voltage drop across the output stage transistors added, the supply voltage must a corresponding 200 watts power amplifier least 85 V be – and under full load. The peak current in the peak of the sine wave is about 10 A, i.e. Stereo operation with 2 amps flowing after all 20 A.

If one is satisfied with an effective Continuous output of 2 x 150 W = 300 W, so has the power of the to be controlled Transformer under consideration a middle-amplifier efficiency 60% accounts for at least 500 VA are. Toroidal transformers offer this especially, since they are very one have low internal resistance, and Therefore, in many cases an additional electronic voltage stabilizer can be dispensed with. Substituting other
