This paper presents a novel high efficiency LED driver.The developed version of the LED driver is based on an active AC-DC converter with a flyback topology.A feature of the proposed circuit is the use of a current / voltage stabilizer on the primary side based on microcontroller FL7733A and a passive stabilizer on the secondary side.The methodology for calculating the rms current values is presented.An experimental sample of the LED driver was designed and assembled according to the proposed scheme.Functional tests have been carried out, which show a qualitative advantage in contrast to the standard circuit of the LED driver.Temperature tests were carried out, it can be seen from them that the driver elements do not experience excessive temperature loads and operate in normal temperature limits.
