Introduction

Dietmar Striegl, an accomplished inventor based in Bad Hall, Austria, has made significant advancements in the field of power inverter technology. With two patents to his name, he has developed innovative solutions aimed at improving the efficiency and functionality of inverters used in electronic and electrical systems.

Latest Patents

Striegl's latest patents demonstrate his expertise and forward-thinking approach in inverter design. The first patent describes an inverter capable of switching between single-phase operation and three-phase operation. This invention aims to enhance the single-phase operation of an inverter, which includes a switching unit that enables the inverter to transition from multi-phase to single-phase operation efficiently. The switching unit facilitates this by closing a center point connection switch, thus connecting the third output pole to the DC link center point. Furthermore, during single-phase operation, it controls the upper and lower power switches of the third phase branch to symmetrize the DC link voltages.

The second patent focuses on a power supply for an inverter and the method for operating such a power supply. This design includes a throttle that connects the output end of the inverter to an electric power supply network, alongside a secondary-side auxiliary winding positioned on the throttle. This setup transmits the output voltage of the inverter to the throttle's secondary side. A comparator unit is also part of the invention, which compares the electric supply network voltage with the secondary-side voltage to determine the appropriate source of electric power, ensuring optimal operation.
