The response time of high voltage impulse dividers is very important parameter which determine their maximal frequency. This parameter has to be tested by measurement in high voltage laboratories. Usually, the step voltage method is used to determine normalized step response and the experimental response time is calculated. Another method is the direct measurement of voltage divider frequency characteristics...
A low power consumption and wide locking range triple-injection-locked frequency divider by two is demonstrated. It consists of triple-injection which combines two features of direct injection and tail injection to enhance locking range. The measured locking range is from 10.18 GHz to 15.49 GHz (41.37%) with an injection power of 0dBm. The measured maximum output power is −3.42dBm with a tuning voltage...
Theoretical analysis has revealed that considerable impact can be found on the operation of ultra high speed machines, caused by subharmonic components. The system studied is applied to generate electric power by utilizing renewable energy resources. The results obtained by numerical calculations were confirmed by computer simulations and also by laboratory tests. The low level of subharmonics, superimposed...
