Post Regulators

The lab investigates the operation of a system comprised of an AC-DC diode rectifier with a cascade of buck and linear post-regulators, and the relationships among physical parameters and operating conditions determining the behavior of the system and the amplitude of input and output current and voltage DC and AC components of each stage.

This is lab 12 of 12 in the course, Power Electronics.

LEARNING OBJECTIVES


After completing this lab, students will be able to:
  1. Given a system composed by an AC-DC diode rectifier, a buck DC-DC regulator and a linear post-regulator, you will calculate the average voltages and currents of each block, with specified units and accuracy, under different setup conditions.
  2. Given a system composed by an AC-DC diode rectifier, a buck DC-DC regulator and a linear post-regulator, you will simulate its operation under different setup conditions, to analyze the average voltage and current and the AC noise.
  3. Given a real system composed by an AC-DC diode rectifier, a buck DC-DC regulator, and a linear post-regulator, you will observe its voltage and current waveforms in different points, and measure the amplitudes of their DC and AC components with specified units and accuracy, to verify the consistency with simulation results and estimate system parameters.
