Abstract
Consistent with an example embodiment, a resonant converter comprises a signalling transformer that is used to transfer information between the secondary winding and primary winding of the converter whilst maintaining mains isolation between the two sides. In the embodiment, according to the disclosure, the use of a signalling transformer (in addition to a switching, or resonant, transformer) eliminates the need for an opto-coupler to transfer information and so allows for the construction of a simpler, more reliable and/or cheaper resonant converter. Other embodiments described herein may be suitable for use in dimmable LED driver applications, for example.
