Latest Patents
One of his latest patents is titled "Systems and methods for power sharing control for direct integration of fuel cells in a dual-inverter EV drivetrain." This invention discloses a dual inverter drivetrain that integrates an energy-storing fuel cell into an electric vehicle. The method described allows for effective operation of the drivetrain using a power sharing control approach, ensuring that the fuel cell's key requirements are met without compromising the vehicle's dynamic performance. This control approach is particularly notable for its ability to maintain unidirectional power transfer from the fuel cell during regenerative braking and to manage fuel cell power despite rapid motor torque changes.
Another significant patent is "Converter modulation for reduction of common-mode leakage current." This invention outlines a method for controlling an electrically symmetrical electric power circuit to minimize common mode leakage currents. The approach involves a controller circuit that manages multiple switches within the power circuit, ensuring that pairs of switches operate in the same state when connected to an electrical grid. This innovation is beneficial for reducing current ripple and overall total harmonic distortion (THD), especially in vehicle-to-grid power transfer scenarios.
