Fig. 4. Efficiency at 48-60Vin, 350W max with 400LFM air flow.
Thermal images with 325W output power at 48Vin with four IRF6635 and two IRF6635
are shown in Fig. 5(a) and (b) respectively. Temperature measurements at different
conditions are listed in table 1. Inputs and outputs of two or more modules can be
connected in parallel to provide required higher output power. Due to natural output
voltage droop associated with open-loop operation, no additional circuitry is required for
accurate current sharing (+/-10%).
(b)Two IRF6635 used on secondary
(a) Four IRF6635 used on secondary.
