The basic principles of launch rheostats construction on semi-conducting thermistors
Incoming article date: 13.04.2018Application of low-power thermal resistors in starters requires availability of intermediate equipment and various components. It significantly reduces the reliability of the equipment. Increase in currents flowing through the pre-regulating devices simplifies electrical schematic of the control and regulation. To use thermal resistors in circuits with high currents it is necessary to use special designs, for the purpose of thermoresistor's material overheating prevention. Algorithms for synthesis of starting rheostats are given. The dependences characterizing different starting models are given.
Keywords: semiconductor thermal resistance, starting current models, generalized current characteristics
