Title: Innovator Patrik Varecha: Advancements in Power Conversion Technology
Introduction
Patrik Varecha is a notable inventor based in Turzovka, Slovakia. He has made significant contributions to the field of power conversion technology. His innovative approach has led to the development of a unique patent that enhances the efficiency of power converters.
Latest Patents
Patrik Varecha holds a patent for a "System and method of estimating temperature of a power switch of a power converter without a dedicated sensor." This invention involves a system for a power switch of a multiphase power converter coupled to an inductive load. The system includes a test controller, a voltage sampling circuit, a processing circuit, and a converter. A test pulse is applied to the power switches of the converter to generate a test current through the inductive load. This process forward biases a body diode of a power switch during a freewheel portion after the test pulse is completed. The voltage across the body diode is sampled during this freewheel portion, and the voltage samples are converted to a voltage value and a slope value. These values are then converted to an estimated temperature value based on the characterization of the inductive load and the body diode. The conversion may be performed using a lookup table that stores an estimated temperature value for each unique combination of the voltage and slope values. This patent showcases his innovative thinking and technical expertise.
