ABSTRACT This study tackles the challenge of managing midpoint potential imbalance and suppressing current zero‐crossing distortion in Vienna rectifiers under conditions unbalanced load. To address this, an adaptive weight model predictive control strategy is proposed. The research begins by analyzing interaction between maintaining balance mitigating distortion, taking into account influences, such as ripple, sampling inaccuracies, load imbalance. A prediction formulated to predict behavior...
Summary A Vienna rectifier is a kind of three‐phase converter with complex operation constraints. Traditional control methods suffer from poor dynamic responses and total harmonic distortion (THD), particularly when operating adjustable wide‐range power. novel low‐complexity model predictive (LC‐MPC) algorithm proposed based on the optimal switching vector sequence in this paper. First, optimization (MPOC) method designed to search for voltage its acting time. Second, equivalent...
Abstract With the increasing attention paid to virtual synchronous generator (VSG) control technology in modern power systems, it not only provides necessary inertia and damping for system but also introduces a new type of low-frequency oscillation mode, which retains characteristics (SG) may exacerbate this phenomenon. In response issue, article proposes an innovative additional controller design aimed at providing effective active SG without affecting steady-state output VSG. By...
Variable-capacitance micromechanical accelerometer is widely used because of its high sensitivity and low power. Therefore, the further study on performance has much theoretical applicable significance. This paper takes closed-loop bias stationary comb-finger variable-capacitance as an example, introduces operation principle, establishes mechanics model through analysis, gives force balance equations. Then it researches analyzes performances such electrostatic forces, full scale, stability,...
