Latest Patents
Dieter Graefje holds a patent for a "Method for a Current Mode Buck-Boost Converter." This inventive method features a current mode control system that employs separate buck and boost pulses for improved performance. One of the key advantages of this technology is its ability to address transient issues in the control loop, thereby preventing voltage overshoots during mode transitions. Additionally, by utilizing a continuous control voltage, the system enhances operational stability. This innovative method also incorporates a strategy where, if the switching occurs in Boost mode and the buck duty cycle is less than a predetermined threshold, the system seamlessly transitions to Buck mode in the subsequent cycle. This design allows for tracking of the Buck comparator output, simplifying the decision-making process based on a singular input.
