Resistors and supercapacitors play an important role in renewable energy applications like wind turbines. The blade of a wind turbine must be adjusted regularly to ensure that the turbine operates at the optimal level in accordance with the wind conditions and to avoid mechanical pressure (stress). Therefore, the propeller pitch control system should be used when necessary. If the power supply fails, the resistor and the supercapacitor can connect and transmit enough energy to return the blade spacing to a safe position and close the turbine, which is not necessarily possible with the battery power supply.

 

 

 

The automotive field is a key market for resistors and supercapacitors, which aid cars to fulfill their functions. Starting / stopping functions and power steering require resistors and capacitors, and hybrid vehicle drives require greater power capacity for both resistors and supercapacitors.
With the continuous development of electric vehicles and entering the mainstream automobile market, the demand for resistors and capacitors will further increase. Future technological advances may allow resistors and supercapacitors to replace lithium-ion batteries as power sources and provide mileage comparable to gasoline and even diesel powered vehicles.
 

Railway industry also began to fully tap technology application potential of resistor and supercapacitor. Trams made by many railway equipment currently use a series of resistors and supercapacitors located in the upper part of the car to recover braking energy-saving 35 percent of electricity. Resistors and supercapacitors can be charged at tram stops without overhead cables, or without cable connections between certain stops.

The development and application of resistors and capacitors have a great impact on many industries. Along with the development of science and technology, the miniaturization design of resistors and capacitors has been continuously tested. At present, many resistors and capacitors have great changes in volume, like precision resistors. Small size precision resistors are widely used in many wind power projects, solar projects and new energy vehicle projects.
