Latest Patents

One of Zipfel's latest inventions is a switching amplifier designed for driving reactive loads. This innovative switching amplifier operates by efficiently driving balanced piezoelectric or capacitive loads, facilitating a compact design that effectively integrates both the amplifier and the transducer in a singular location. By employing two or more transducers with phase-shifted signals, the power supply current is minimized, allowing for intelligent energy management that cycles stored energy between transducers rather than routing it through power supply lines. The modulation scheme of the amplifier cleverly positions switching frequencies in common-mode while baseband signals operate in differential mode, enhancing efficiency. The technology further reduces the physical size of auxiliary components, yielding low-volume load filters that require only minimal energy storage.

The second patent by Zipfel involves a method of forming platinum contacts on In-based Group III-V compound devices. This process involves electron beam depositing a thin Pt layer directly on semiconductor materials such as p-InGaAsP, followed by sintering at precision temperatures. This innovative technique results in light-emitting diodes that are free from dark spot defects, enhancing performance and reliability in various applications.
