考虑IEC 61800-3传导和辐射发射限制的无屏蔽电机电缆三相Buck-Boost Y型逆变器VSD的EMI滤波器设计

The standard converter concept employed in variable speed motor drives is the two-level three-phase Si insulated-gate bipolar transistor voltage source inverter with its switch nodes connected to the motor terminals via shielded cables to avoid excessive high-frequency noise emissions. However, high dv/dt pulses of the inverter pose substantial stresses on the motor, which are further intensified ...
