摘要

本文研究了一种基于自定义IPM的电梯逆变系统的优化设计。所提出的方法降低了dv/dt和di/dt，从而在没有额外电路的情况下最小化传导EMI噪声。它只优化嵌入在IPM中的IGBT中栅极电阻的值。为了将定制的IPM优化到电梯系统，我们模拟并测量了尖峰电压和电机浪涌电压，包括由于IPM外壳和散热器的开关损耗引起的温度变化。因此，由于栅极电阻对IPM的优化值，传导的电磁干扰噪声降低了大约。5/spl sim/10 [dB/spl mu/V]在特定频域。

Optimal design and minimization of conducted EMI noise in elevator inverter system by customized IPM

This paper deals with the optimal design of an elevator inverter system based on a customised IPM. The proposed approach reduces dv/dt and di/dt resulted in minimization of conducted EMI noise without an additional circuitry. It only optimises the value of gate resistor in the IGBT embedded in the IPM. In order to optimise the customized IPM to an elevator system, we simulated and measured the spike voltage and the motor surge voltage including the temperature variation due to the switching losses at the IPM case and heat-sink. As a result, thanks to the optimised value of the gate resistor to the IPM, the conducted EMI noise is reduced approx. 5/spl sim/10 [dB/spl mu/V] in a particular frequency domain.
