What are the different circuit in a power amplifier?

Power amplifier circuits (output stages) are classified as A, B, AB and C for linear designs—and class D and E for switching designs. The classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current.

What are the requirements of power amplifier?

It is required to deliver a large amount of power and has to handle large current. The base of transistor is made thicken to handle large currents. The value of β being (β > 100) high. The size of the transistor is made larger, in order to dissipate more heat, which is produced during transistor operation.

How can I increase amperage without increasing voltage?

Use a conductor that has low resistivity. The conductor can be used for a small length. Use a thick wire.

What is audio amplifier circuit?

The circuit of the audio amplifier consists of a transistor a device to apply the input signals and a speaker at the output. The transistors are connected based on the necessity. The important factors that need to be considered while designing a audio amplifier is gain,noise, frequency response and distortion.

How many dB is 150 watt?

Watts (W) to decibel-milliwatts (dBm) , power conversion calculator. The power P(dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P(W) in watts (W) divided by 1 watt (W): P(dBm) = 10 ⋅ log 10 ( 1000 ⋅ P(W) / 1W) = 10 ⋅ log 10 ( P(W) / 1W) + 30
