Abstract: The invention proposed a space vector pulse width modulation (SVPWM) method for any level cascaded H-bridge inverter. The multilevel space vector diagram is re-divided, and the coordinates of the nearest three vectors (NTVs) are directly obtained by judging the position of the reference vector. The duty cycles of the NTVs is calculated through additional vector which is equivalent to the reference vector. Then, the switching states are obtained by zero-sequence component and coordinate transformation, and the desired reference vector is synthesized for the SVPWM modulation. The invention realizes multilevel modulation in Cartesian coordinates without any iterative calculation, and the calculation is independent of the level number. Furthermore, the locating of the reference vector and the calculation of the duty cycles are simplified, and the calculation complexity is reduced.

Abstract: A method and a system are presented for controlling a performance of a fusion model. The method includes obtaining a first set and a second set of candidate models for a first and second neural networks, respectively. Each of the first and second set of candidate models is pre-trained with a first source and a second source, respectively. For each possible pairing of one candidate model from the first neural network and one candidate model from the second neural network, a model distance Dm is determined. A subset of possible pairings of one first candidate model and one second candidate model is selected based on the model distance Dm between them. Using the subset of possible parings, the first neural network and the second neural network are combined to generate two branches for a fusion model neural network.

Abstract: A class of improved solid-state electrolytes and methods for forming such electrolytes are discussed herein. The improved electrolytes may be a sodium oxy-sulfide, such as with a nominal composition of Na3PS4 _xOx (0<x?2). The electrolytes can be synthesized from using a simple one-step ball-milling method. The ball-milling may be performed at high rotation speeds. The resulting ball-milled materials may further be optionally pressed. The pressing may be performed at low or room temperatures and/or relatively low pressure, and the resulting electrolytes achieve high relative densities. The solid-state electrolyte forms a highly dense layer that approaches a continuous glass that is nearly flawless, is mainly amorphous, and/or maintains a stable low-resistance interface with Na metal and Na-alloy electrodes.
