Course Description

072-Switchmode Boost Power Converter Using Current-Mode Control

The Switchmode Boost converter is used widely for high efficiency conversion of DC power available at a lower voltage and delivered to a load at a higher voltage. This course develops models of the Boost converter with current-mode control. Basic operation, a practical of example, and large/small signal models are discussed. The considerations for control of the converter are introduced.

The selection of appropriate inductor and capacitor values are discussed, considering the frequency of operation and other design parameters. A constant-frequency Pulse-Width Modulator (PWM) controller is employed. We develop the feedback conditions for frequency-domain, small-signal, stability in the open-loop model and include a Pole-Zero (PZ) compensator for good margins. We introduce the Zero-Order-Hold (ZOH) effects of the inherent sampling caused by cycle-by-cycle control and include those effects in the (PZ) compensator. Current-limit control is introduced and used as the basis for the introduction of cycle-by-cycle current-mode control. The loop is closed and a "soft-start" capability added to high inrush currents during startup. Line and load regulation are shown for the example as well as transient load recovery. The need for "Slope Compensation" is introduced and explained and an example shown contrasting behavior with and without it. The material covered should enable a working engineer to construct a stable Boost converter using current-mode control.

This group of 4 courses are about the best on-line courses I have taken. They are very technical. I doubt that many people can complete them in the four hours for which they are rated.
