恒转矩工作的电力传动中变频器的选择

A Selection of Inverter in the Electric Power Drive Working with the Constant Torque

在恒定转矩工作和频繁起动的可变速电力传动中,对变频器的选型问题进行了研究,并提出了评估变频器功率损耗的数学模型,通过实验,验证了数学模型的适用性。

Questions of a choice of the inverter for variable-speed electric drive, working with the constant torque and the frequent start are considered. The mathematical model for an estimation of power losses in the frequency converter is offered. A applicability of the mathematical model is demonstrated by experiments
