Study on the Real-Time Sampling System of PWM Voltage in the Power Hardware-in-the-Loop System
Abstract: In the PHIL system, real-time sampling for PWM wave voltage is the base of real-time digital simulation. Instantaneous sampling was no longer applicable, while low-pass filter sampling would bring sampling delay and caused system instability. A mean time-domain sampling system was presented, and its sampled voltage waveform was analized to optimize selectting the sampling frequency. The theoretical analysis and simulation results showed that: The sampling method could accurately extract the equivalent component of the PWM voltage, and the sampled voltage waveform distortion could be inhibitted by optimizing the sampling frequency. The simulation results verified the effec- tiveness and feasibility of the sampling method.
