Latest Patents

Sina holds a patent titled "Adaptive pulse width modulation overmodulation in three-phase voltage source inverters." This method involves voltage vector command values for an electric motor implemented on a vehicle operating in a linear region. The process includes receiving system state information of the vehicle and determining if an overmodulation threshold is satisfied based on this information. Upon confirming that the threshold is met, the method calculates a modulation factor from a modulation index, generates a three-phase output based on the voltage vector command values and the modulation factor, and determines a series of control signals corresponding to the switches of an inverter. Ultimately, the method instructs the switches to control the electric motor's operation in the overmodulation region.
