Title: Johann Galic: Innovator in Pulse Width Modulation and Motor Control Systems
Introduction
Johann Galic is a notable inventor based in Surahammar, Sweden. He has made significant contributions to the fields of pulse width modulation systems and motor control technologies. With a total of 4 patents to his name, Galic's work reflects a deep understanding of electrical engineering and innovative design.
Latest Patents
One of his latest patents is a pulse width modulation system provided with synchronized control boards. This system includes multiple module building blocks, where one control board acts as the master and the others as slave control boards. Each slave control board determines a fictive master board timer based on information received via a communication bus. This synchronization minimizes variations in predetermined operation parameters related to loads connected to pulse width modulated phase outputs of function modules.
Another significant patent is a method for determining the position of a freely rotating rotor in a permanent magnet motor. This method involves short-circuiting the windings of the stator and measuring the back electromotive force (EMF) of the short-circuited windings. By analyzing the measured back EMF, the position of the rotor can be accurately determined, enhancing the efficiency of motor control systems.
