1000W Power Amplifier 2SC5200 2SA1943

Hello, all royal visitor, in this post I will share a post about the 1000W mono power amplifier using 2SC52000 transistor and 2SA1943 as the final transistor. In this 1000W power amplifier has a transistor amplifier configuration with emitter commons. A little explanation of the emitter commons reinforcement which means is a circuit with emitter pins connected together. In the emitter common configuration, base transistor pins are used as inputs while the collector pin section is used as output.

And the following is the circuit along with a list of components of the 1000W Power Amplifier:

Transistor amplifier with common emitter configuration is one of the most widely used configurations compared to a common base and common collector, Whether it is for audio, video, high-frequency amplifier, and others. This is because the amplifier with common transistor emitter configuration will amplify the current and voltage simultaneously.

The input signal to the output on the common emitter is reversed phase. Thus making it more powerful power amplifier, and to discharge power up to 1000W Power Supply will require a capable, if not then the power will be a useless or wasteful component when compared with a good power supply. For example, the power supply is used at least 10A 55V. And to add more power you can upgrade the final part of 2SC5200 and 2SA1943 transistors into more. Thank you and Good Luck.
