Latest Patents

Tobias Rogg holds a patent for a "Method and system for estimating differential inductances in an electric machine." This self-commissioning method is designed for estimating differential inductances in electric machines, such as synchronous reluctance machines or interior permanent magnet machines, while considering cross-magnetization effects. The method involves driving the electric machine with PWM voltages to explore various operating points while maintaining the machine at standstill or quasi-standstill. By utilizing PWM switching voltage transients as small-signal excitation, the currents of the electric machine are measured through oversampling, allowing for the reconstruction of waveforms, including current ripple within a PWM period. Ultimately, the differential inductances at each operating point are determined based on the direct and quadrature current waveforms and voltages.
