Philip Michael Johnson is a notable inventor based in Brighton, MI (US). He has made significant contributions to the field of electrical engineering, holding a total of 5 patents. His work focuses on advanced power conversion technologies that enhance the efficiency and functionality of electrical systems.

Latest Patents

Johnson's latest patents include an "Active filter for single phase charging using a switch-mode converter." This invention provides a converter for electrical connection to both three-phase and single-phase electrical grids. The converter features three DAB modules, each responsible for converting the alternating current from a three-phase electrical grid. When connected to a single-phase grid, the third DAB module operates bi-directionally to filter the power output of the first and second DAB modules. Additionally, the converter includes a filter capacitor in communication with the third DAB module through a relay, which is controlled to switch between the filter capacitor and a grid rectifier based on the detected grid type.

Another significant patent is the "Half-bridge with variable dead band control and zero-voltage switching." This invention presents an improved method for zero-voltage switching (ZVS) of a voltage-fed half-bridge using a variable dead band. The method dynamically determines the duration of the dead band to prevent shoot-through events while minimizing switching losses. It involves calculating the equivalent capacitance, ZVS charge requirements, and updating the dead bands for each commutation in the switched-mode power converter.
