Abstract

As a result surveying’s, of calculations and measurements, mentioned in this article, was analyzed the capability of application as PWM the controller of microcircuit L6562 frequently been used the designers of светодиодных illuminants in connection with its operational reliability, simplicity схемотехнической implementation and low value. However in investigated светодиодном the driver of office illuminant, in the application of this microcircuit in the transient behavior of the operation of the adjusters of phase factor with the utilization of the means of voltaic cross coupling between feed-in mains and output termination, appeared the necessity of the correction of the typical chart of the inclusion of values PWM controller for the improvement of it performance according to the State Standard IEC 61000-3-2: 2004 .
Then were determined networks being subject correction, for which were calculated the performance of RC networks as a result what managed to bring down the coefficient of the harmonic deformations of incoming current practically twice as well as to avoid the deformations of the form of the sinusoid of incoming current which led to the additional gain of the value of the coefficient of the correction of power in 100% the load of inductor.
