Title: Innovations of Henricus Cornelis Johannes Buthker
Introduction
Henricus Cornelis Johannes Buthker is a notable inventor based in Mierlo, Netherlands. He has made significant contributions to the field of electrical engineering, particularly in the development of boost converters and DC-DC converters. With a total of 16 patents to his name, Buthker's work has had a considerable impact on power management technologies.
Latest Patents
One of his latest patents is the "Constant on-time boost converter." This invention features a comparator circuit that includes a first input port for an off-time sawtooth voltage and a second input port for an on-time sawtooth voltage. The comparator circuit compares these voltages to generate a trigger signal, which includes a differential ripple voltage output to a power stage circuit. Additionally, the boost converter comprises a reference voltage source and a feedback circuit that provides the on-time sawtooth voltage, allowing the differential ripple voltage to emulate an inductor current or voltage of an output capacitor.
Another significant patent is the "Controller for a DC-DC converter." This controller is designed for a DC-DC converter that includes an inductor and operates in three phases. The first phase involves charging the inductor with an input voltage, the second phase discharges the inductor to a load, and the third phase disconnects the inductor from the load. The controller sets a control-factor based on the input voltage and adjusts the duration of the third phase accordingly.
