Title: Tufan C Karalar: Innovator in Power Conversion Technologies

Introduction

Tufan C Karalar is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of power conversion technologies, holding a total of 5 patents. His work focuses on enhancing the efficiency and reliability of voltage converters and motor drive circuits.

Latest Patents

One of his latest patents is for a "Soft-start for isolated power converter." This invention involves sensing the current flowing through an inductor on the primary side of a voltage converter and comparing it to a threshold peak current value. This process determines when to end the ON portion of the voltage converter. The secondary side of the converter supplies an indication of output voltage, which is crucial for determining the threshold peak current value. During start-up, the primary side detects when the secondary side provides this indication across an isolation channel. Before this detection, the primary side uses an increasing threshold peak current as the threshold value. Once the output voltage indication is detected, the threshold peak current value is adjusted based on this indication.

Another significant patent is for a "Soft shutdown for isolated drivers." This apparatus controls a high-power drive device external to a motor drive circuit package. The motor drive circuit includes a driver that manages the high-power device based on reference voltages and a control signal. A fault circuit generates a failure indicator based on the voltage across the device's terminals, determining a fault condition. The driver charges and discharges the node of the high-power device over different lengths of time, depending on the fault condition and control signal levels.
