Flyback or forward quasi resonant mode

Energy conversion

Our expertise and capability in specific customer requirements, allows us topropose a large range of innovative solutions from1W to fewKilowatts, in power supplies, DC to DCconverters andbattery chargerswith mono or multiple outputs.


The use of classical topologies as flyback or forward modes allows getting robust and economic electronic products, with high MTBF.
For applications requiring to be kept in high temperature conditions, large efficiency requirements or strict characteristics of electromagnetic compatibility (EMC), we use symmetrical type topologies, as for example quasi resonant mode, which can if needed, be coupled with synchronous rectification.

These products are often built with active or passive type PFC, with different modes of functioning (continuous, discontinuous, medium), to enable a large input voltage range and a form factor complying with international regulations.
