Latest Patents

One of Acharya's latest patents is titled "Gate driver circuits with independently tunable performance characteristics." This invention provides a gate driver circuit that includes a turn-on path, a turn-off path, and a fast discharge path. The turn-on path is couplable between a gate of a solid-state switch and a voltage turn-on signal (VG) from a gate driver, defining a turn-on time for the solid-state switch. The turn-off path is couplable between the gate and a voltage turn-off signal (VG) from the gate driver, defining a turn-off time for the solid-state switch. The fast discharge path is selectively couplable in parallel with the turn-off path during a portion of a gate-to-source voltage (V) transition for the solid-state switch, allowing for independent configuration of turn-on time, turn-off time, and turn-off delay.

Another notable patent is "Voltage rate-of-change control for wide-bandgap-based inverter circuits for driving electric motors." This invention describes an insulated gate field effect transistor (IGFET) based converter circuit that includes a direct current input comprising a high voltage input and a low voltage input. The circuit features an equivalent phase leg comprising a plurality of parallel-connected cells, each containing wide bandgap IGFETs and a step-inducing inductor connected to the output node.
