560V Input, No-Opto Isolated Flyback Converter
560V Input, No-Opto Isolated Flyback Converter
24.07.2017 · Circuits
In traditional isolated high voltage flyback converters, tight regulation is achieved using opto-couplers to transfer regulation information from the secondary-side reference circuitry to the primary side. The problem is that opto-couplers add significant complexity to isolated designs: there is propagation delay, aging, and gain variation, all of which complicate power supply loop compensation and can reduce reliability...
