Latest Patents

One of his latest patents is titled "Derating Control of a Power Inverter Module." This invention includes a system that features a DC battery pack, an inverter coolant loop, first and second temperature sensors, a polyphase electric machine, and a power inverter module (PIM) connected to both the battery pack and the electric machine. The PIM consists of multiple semiconductor switches, and the controller is designed to selectively derate the PIM, thereby reducing the commanded torque to the electric machine. The controller executes a method to receive coolant temperature from the first temperature sensor and PIM temperature from the second temperature sensor. It estimates the junction temperature of the semiconductor switches based on these temperatures and the set of electrical values, allowing for selective derating when the PIM temperature exceeds a calibrated maximum.

Another significant patent is the "Inverter Circuit for an Electric Machine." This invention establishes an inverter circuit that connects a high-voltage bus to a multi-phase electric machine, incorporating several switch pairs. Each switch pair consists of a first switch connected in series with a second switch at a node, which connects to a phase of the multi-phase electric machine. The first switch is configured as a normally-OFF switch, while the second switch is a normally-ON switch, enhancing the efficiency and functionality of the inverter circuit.
