Expert ID: 723924 Israel

Request Expert

He has developed recently an AC-to-DC high power converter using a very modern and reliable low-switching-loss topology including special magnetic design, use of high voltage power mosfets and fast voltage/current loops optimization by means of very detailed mathematical means and simulations, all of them being close to the practical results.


The converter was incorporated in an special application with special care for: input voltage surges and protections against lighting interferences on both Input and Output connections; high reliability; high efficiency; proper thermal design; mechanical modular concept.


He has designed the analog and analog-digital circuitry for all regulation, pulse-width-modulation; pulse drivers; overvoltage and overcurrent protections; bias circuitries; magnetic components etc.

Array

He has developed the main 5KW power platform for a start-up company which will use it for their research work.
The work included: mechanical placement, layout design, RFI design, magnetic components design, some SPICE simulations.He has designed the backplane of a R.F base station with following issues: modular redundant power supply for all channels, analog, digital and R.F ground layers placement.
