Abstract
The present invention provides a system, method and apparatus for controlling any type of converter using input-output linearization and leading-edge modulation. The controller includes a summing circuit connected to the converter to create a third voltage representing a difference between the first voltage and the second voltage. A gain circuit is connected to the summing circuit to adjust the third voltage by a proportional gain. A modulating circuit is connected to the gain circuit, the converter, the second voltage and the second current to create a control signal based on the second voltage, the adjusted third voltage, the first current and the second current. The control signal is used to control the converter. Typically, the first voltage is an output voltage from the converter, the second voltage is a reference voltage, the first current is an inductor current from the converter and the second current is a reference current.
