基于逆变器dv/dt电流测量噪声引起的信号注入无传感器控制位置估计误差分析

This article discusses position estimation error in signal-injection sensorless control (SISC) induced by the current measurement noise of closed-loop Hall effect current sensor, when it is installed in an inverter system. For the first step, an equivalent circuit modeling of the current sensor in the inverter system is proposed, which includes the parasitic capacitances between the inverter and s...
