What is class A output stage? Where are class A amplifiers used?
A Class A amplifier stage passes the same load current even when no input signal is applied so large heatsinks are needed for the output transistors. These types of devices are basically two transistors within a single package, one small “pilot” transistor and another larger “switching” transistor.
The Class A Amplifier more suitable for outdoor musical systems, since the transistor reproduces the entire audio waveform without ever cutting off. As a result, the sound is very clear and more linear, that is, it contains much lower levels of distortion.
How to Calculate Power conversion efficiency of an output-stage?
Power conversion efficiency of an output-stage calculator uses power_conversion_efficiency = Load Power/Supply Power to calculate the Power-conversion efficiency, The Power conversion efficiency of an output-stage formula is defined as the proportion of the area under the I-V curve of a PV cell to the input illumination intensity. Power-conversion efficiency and is denoted by η symbol.
How to calculate Power conversion efficiency of an output-stage using this online calculator? To use this online calculator for Power conversion efficiency of an output-stage, enter Load Power (PL) and Supply Power (P_{s}) and hit the calculate button. Here is how the Power conversion efficiency of an output-stage calculation can be explained with given input values -> 0.012 = 6/500.
