100W auxiliary power supply

From solar to high power industrial

This 24 V/100 W auxiliary power supply with reinforced isolation guarantees reliable operation in HV industrial applications up to 690 VAC, as well as the now common photovoltaic applications using a 1kV DC bus.
These power supplies often power critical systems like control units, gate drivers, communication and safety functions, and must therefore offer a high degree of reliability and robustness as well as maximum possible efficiency.

This converter implements a flyback topology based on the L6566BH PWM controller and features high voltage startup functionality and the rugged MDmesh K5 series of very high voltage MOSFET to withstand voltages exceeding 1.5kV.
