For the specifications below, what architecture/topologies would you use?
Power Supply Architecture 400 W Manager's Choice
4 x 35 V output all isolated, 5% regulation Slow turn on after 30 second delay. Overcurrent protection needed. 400 W total power on these outputs
+/-60 V output 1% regulation ground reference. Must come up first. 5 W total power
12 V Output. 30 W total power ground reference. Comes up with 60 V output. 5% regulation.
Control bias as needed.
120 - 240 VAC input
Performance far more important than price. High density and low-noise a plus.
If using something like Vicor building blocks, how would you incorporate sequencing and protection? What are the "gotchas" with their parts?
If building discrete power, what would your preferred sequencing and protection be?
