Power Supply Design: 10 years of experience
C&D Technologies. Pioneer Magnetics. Unisys. Contract Work.
Released several PSU designs in the Medium and High power range with PFC.
Wide power range from 150W to 2KW single phase and 5KW to 15KW 3 phase.
Embedded, low power single stage units in the 100W range.
Topologies: Flyback, Forward, Half Bridge, Full Bridge, ZVS, ZVC & Resonant.
Serial / Parallel PFC: 5% efficiency improvement and lower component stress.
Each half PFC section sees only a range from 85VAC t0 160VAC.
Significant help for a very wide range design from 85VAC to 305VAC.
Invented 2 new Topologies, 1st for isolated AC–DC, 2nd for non-isolated DC-DC.
2 to 1 size reduction of a VRM multiphase Buck converter.
Familiar with: Current Sharing. N+1 Redundancy. Hot Swap.
EMI compliance. MTBF calculation. Safety Approval.
System Architecture: 3 years of experience
Unisys.
Developed a Power System Architecture for the Unisys mainframes.
Voltages in the 5V range & currents up to 5000A per rail.
N+1 Redundancy. Hot Swap.
Reduced number of different units and subsequent inventory by a factor of 4.
Redundancy design, impact and cost optimized through MTBF calculation.
This has been a determining factor for the selection of Burroughs Rancho Bernardo over Sperry Dorval during the Burroughs Sperry merger into Unisys.
Power Lighting: 5 years of experience
Exclara. Grimes Aerospace. Contract Work.
Designed a series of multichannel Power LED Drivers for In & Outdoors Lighting.
Power Range 30W to 250W Single and Multi Channels.
Patented a redundancy system for several LED strings on a single channel unit.
This technique allows to have the 4 channels in series (normally reaching 240V) forming a single current controlled loop and still be SELV (under 60V).
Use of a unique technique for Lightning Protection increasing several folds the clamping efficiency of the MOV by compensating for the serial impedance.
Invented a new Topology ganging 3 different stages into a Single Stage unit.
The Single Stage with a Single Magnetic provides a 50% Cost & Space Reduction.
Developed Strobe Light Systems for Boeing and...
