The packaging problem with petroleum-based synthetic polymers prompts the development of edible packaging films. The high value-added reuse of navel orange peel pomace, which is rich in bioactive compounds, merited more considerations. Herein, nanocellulose (ONCC) and soluble dietary fiber (OSDF) from navel orange peel pomace are firstly used to prepare dietary fiber-based edible packaging films using a simple physical blend method, and the impact of ONCC on the film’s properties is analyzed. Adopting three methods in a step-by-step approach to find the best formula for edible packaging films. The results show that dietary-fiber-based edible packaging films with 4 wt.% ONCC form a network structure, and their crystallinity, maximum pyrolysis temperature, and melting temperature are improved. What’s more, dietary-fiber-based edible packaging films have a wide range of potential uses in edible packaging.

The electromagnetic interference (EMI) issues in motor drive system are becoming increasingly serious as a result of the rising integration and power density requirements for motor drives. In order to handle the EMI issues in the motor drive system, it is necessary to determine the conducted EMI of the system. Therefore, the conducted interference prediction model of the motor drive system is established in this paper. First, the conducted interference path of the motor drive is analyzed. Then, the conducted interference prediction model of the drive system is accurately modeled, including the measurement equipment line impedance stabilization network (LISN), inverter, cable and motor. To accurately simulate the electromagnetic field in the system, the high-frequency characteristics of the capacitors and the parasitic parameters between the inverter and the heat sink are considered. Finally, the motor drive system is simulated with MATLAB/Simulink, and the simulation results agree better with the experimental measurements.
