Experimental testing new high performance led driver

Abstract

This article introduces a new high-performance LED driver. The developed version of the LED driver is based on an active AC-DC converter with a reverse-pass topology. A special feature of the proposed scheme is the use of a current/ voltage stabilizer on the primary side based on the FL7733A microcontroller and a passive stabilizer on the secondary side. The method of calculating the current values of the current value is presented. According to the proposed scheme, an experimental sample of the LED driver was designed and assembled. Functional tests were carried out, which show a qualitative advantage over the standard LED driver circuit. Temperature tests were carried out, and it is clear that the driver elements do not experience excessive temperature loads and operate within normal temperature limits.
