Power Amplifiers

This lab focuses on the amplifiers used to drive the brushed DC motor. The first section of the lab outlines the operation of a linear power amplifier, with a focus on the simplicity of the operation. The second section introduces the operational theory of the pulse width modulation amplifier, with a focus on the comparative performance of this amplifier. The two amplifiers are finally compared in the context of actuator efficiency and control.
