Abstract: A system for active damping in a steering system includes a multi-phase inverter circuit associated with a motor. The multi-phase inverter circuit includes a power circuit and at least one bipolar junction transistor. The system also includes a processor, and a memory. The memory includes instructions that, when executed by the processor, cause the processor to: receive a torque signal corresponding to a torque applied to a handwheel; generate a damping signal based on the torque signal; and selectively control current flow to the at least one bipolar junction transistor based on the damping signal.

Abstract: One or more embodiments are provided for an inverter. The inverter includes a phase switch configured to supply AC power via an output terminal. The phase switch includes a high-side leg and a low-side leg. The high-side leg includes a high-side solid-state switch configured to selectively conduct current between a high-side conductor of a DC bus and the output terminal, and the low-side leg includes a low-side solid-state switch configured to selectively conduct current between the output terminal and a low-side conductor of the DC bus. The high-side solid-state switch has a first conducting-state resistance value, and the low-side solid-state switch has a second conducting-state resistance value different than the first conducting-state resistance value. A shunt resistor may be connected in series with a corresponding one of the high-side solid-state switch or the low-side solid-state switch, balancing the resistances of the high-side leg and the low-side leg.
