Latest Patents

Among his latest patents is the "Pulse-width modulation signal observation circuit and hardware-in-the-loop simulation device having the same." This invention provides a hardware-in-the-loop (HIL) simulation device that includes a processing circuit and a pulse-width modulation (PWM) signal observation circuit. The PWM signal observation circuit features an energy storage unit that is coupled to the processing circuit. A signal source transmits a PWM signal to both the processing circuit and the PWM signal observation circuit, charging the energy storage unit when the PWM signal is at a high level. The processing circuit detects the voltage of the energy storage unit when observing the falling edge of the PWM signal to calculate the duty cycle of the PWM signal.

Another significant patent is the "Motor parameter estimation device and method." This method involves obtaining an operation signal of a motor, which includes an encoder signal, a phase current, and a driving voltage. The process includes obtaining the number of poles based on the encoder signal and phase current, performing a simulation procedure according to the driving voltage, number of poles, and an initial random parameter set. The simulation procedure calculates a simulation response current and determines an error value between the simulation response current and the phase current. If the error value falls outside a threshold range, the simulation procedure is repeated with an updated random parameter set until the error value is within the threshold range, at which point the number of poles and the initial random parameter set are output.
