Electronics Help Care Amplifier circuit diagram Class-D power audio amplifier 500 watts:
This is a Class-D power audio amplifier 500 watts. This circuit diagram can make a maximum of 600 watts using 200 volts. It’s a mono circuit diagram. Here, use IRS20124’s IC for the driver circuit. and an IRFP260N MOSFET for the output. This circuit needs two voltages, one for the driver section and another for the output section. 20 supply is needed for the driver section, and a minimum of 80 volts to 200 volts is needed for the output MOSFET.
1200-watt amplifier circuit diagram:
This is a 1200-watt amplifier circuit diagram using MJL21193 and MJL21194. Here, use 12 transistors. 6 pairs of transistors. One pair of transistors can make 200 watts. Also, 2SC5200 and 2SA1943 were used for the driver transistors. This voltage is 80. And the amperes are 15. We know that Voltage X amperes = Watts. Then the watts are 80X15 =1200. A strong voltage and amperes can make a strong watts. An amplifier circuit is a way to convert voltage to sound.
This is the Speaker protection circuit diagram. It can protect our Speaker from burns. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker
How to add an extra transistor? A Maximum transistor amplifier can add extra transistors, but it will not work if we don’t increase the amperes or voltage. If we want to add an extra transistor, then we have to increase the voltage and amperage. like the voltage is 35-0-35 and 3 amperes for 2 transistors. If we add an extra 4 transistors, then we have to add an extra 4 amperes. And the voltage can be 45-0-45 maximum.
This is a 2-transistor amplifier circuit for 100 watts of output. in this board used 2sc5200 and 2sa1943 transistors. We can use 20-0-20 voltage to 60-0-60 voltage in this board. It’s a mono diagram. It would help to always have the best quality transformer diode and capacitor to make a strong voltage. We can get the strong watts for the strong voltage. This is an audio transistor circuit diagram of 2SC5200 and 2SA1943. It’s a mono amplifier. This amplifier can make 100 watts. NPN and PNP are used. We can also use other NPN and PNP transistors. Here in this amplifier, we can use a 20-0-20 voltage to a 50-0-50 voltage and 4 amperes. For the stereo amplifier, we need a dual circuit. We know that voltage X amperes = watts. Then 20 volts 3 amperes 20X3 = 60 watts. 30X3=90 watts. Normally, we can use a 35-0-35 voltage to get a good performance.
