“…Three-phase PWM VSR systems have been incrementally applied in the field of renewable energy systems, uninterruptible power supplies (UPSs), motor drivers, and so forth and have become an indispensable energy conversion device (Yang et al, 2016;Li and Yang, 2017;Bueno and Pomilio, 2018;Zhang et al, 2021). However, most of the renewable energy equipment is built in the mountains or remote areas away from the coast as the probability of sensor faults is very high under harsh climates or conditions (Bidadfar et al, 2021).…”

Three-phase PWM voltage-source rectifier (VSR) systems have been widely used in various energy conversion systems, where current sensors are the key component for state monitoring and system control. The current sensor faults may bring hidden danger or damage to the whole system; therefore, this paper proposed a random forest (RF) and current fault texture feature–based method for current sensor fault diagnosis in three-phase PWM VSR systems. First, the three-phase alternating currents (ACs) of the three-phase PWM VSR are collected to extract the current fault texture features, and no additional hardware sensors are needed to avoid causing additional unstable factors. Then, the current fault texture features are adopted to train the random forest current sensor fault detection and diagnosis (CSFDD) classifier, which is a data-driven CSFDD classifier. Finally, the effectiveness of the proposed method is verified by simulation experiments. The result shows that the current sensor faults can be detected and located successfully and that it can effectively provide fault locations for maintenance personnel to keep the stable operation of the whole system.

This work studies the use of single-phase high power factor PWM rectifiers in aircrafts with variable frequency (360 to 800 Hz) power generation. It also presents design guidelines for input and output filters, and discusses the modeling and design of the voltage and current controllers. A 1 kW system is simulated considering a variable frequency grid, verifying the compliance with the aircraft power quality standards. Experimental results from a prototype allows to verify the design procedures.
