摘　　要：对无损耗电阻器的特性和功能作了分析和探讨,建立了无损耗电阻器的数学模型及应用补偿算法。由于无损耗电阻器可由理想开关阵列和电路储能元件组成,所以损耗极小。利用无损耗电阻器可节省能源的特性,将无损耗电阻器代替电阻器用于负阻性电路系统中,实现了负阻性电路系统的稳定,减少了电路中的能量损耗,并可控制系统的响应时间。实验结果验证了特性分析和补偿算法的正确,说明无损耗电阻器可用于实现具有不稳定极点的各类电系统和自动控制系统的稳定。The characteristics and function of Loss-Free Resistor (LFR) are introduced.The mathematical model and associated algorithm of Loss-Free Resistor are also given.The Loss-Less Resistor is realized using a switch mode circuit technique and a storage element to reduce the lose of LFR.LFR can be used to replace conventional resistors to stabilize a given circuit with Negative Resistive Characteristics.The energy Loss of the circuit can be reduced and the respond time of the circuit can be controlled by using the LFR.The validity of the characteristic analysis and the applicability of algorithm have been proved by simulation.Therefore, the LFR may be applied to stabilize electrical systems and automatic control systems with a constable pole characteristics.
