Course Description

062-Switchmode Buck Power Converter Using Voltage-Mode Control

This course covers a methodology for designing a Switch-Mode Buck power converter employing a voltage-mode feedback control approach. The Buck power conversion topology is introduced and considerations for selecting inductor and capacitor components essential for efficient energy transfer are discussed.

Topologies for two states of switching are shown and a state-space averaged model is produced. A small-signal model linear model is produced to examine potential stability issues. Zero-Order Hold (ZOH) effects of the discrete-time nature of switching within the control loop are included. Pole-Zero (PZ) compensators necessary to stabilize the open-loop characteristics of converters with disparate switching frequencies are designed.

The Pulse-Width Modulator (PWM) is introduced it into the feedback loop. Both feedforward and feedback capabilities are added to the PWM and contrasted.

Text refers to figures 18.2 & 19.2; figures not present in my copy. Test question 24.... equation 10.1 calculates inductor value for 100 milliamp peak to peak ripple current, test question increases ripple to 200 milliamp with all other parameters the same, Current is in the denominator so how is the inductor value larger for question 24?

This is very technical, but what I wanted. The course booklet has some English errors and could do with some clarification and improved readability.

This is a good course overall. The units are not displayed correctly in several test questions and they are not clearly displayed on the test. Using the wrong units will result in missing the correct answer. Also, it is difficult to be certain of the correct answer to several questions due by reviewing the course material.
