Experience:

As a Magnetic Design Engineer, for 30 plus years, I have designed a large number and variety of power systems and transformers & inductors.  This process has included:

·              Magnetics Design: building prototypes, writing assembly procedures, preparing drawings and testing finish designs and production samples.  Tools: Ansys, Ansoft, Intusoft, Infolytica and Maxwell’s equations.

·              Real working knowledge of metal machining and plastic injection modeling both in-house and working on-site with sub-tier suppliers.

·              Detailed knowledge of chemical damage/corrosion of polymers and metals (leaching, tin whiskers & Dendritic growth)

As an analog circuit designer, my work has been with discrete components. I have experience in Magnetic and Optical sensors, as well as Analog & D/A converters.  I also have more than a passing knowledge of IC (Wafer) Fab., this includes working with IC makers on new ASIC's.

Designed Linear and Switching Power Supplies used in a wide variety of applications for Aircraft, Military, Commercial, and Industrial.  Typically the designs were low power DC/DC converts.  However, I have over two years of experience in the design and development of High Energy Capacitive Discharge circuits (Exciters [Ignition systems for Jet Aircraft]) with stored energy levels over 100 Joules.

Have worked directly with manufacturing & quality control to develop procedures, start new projects and solve problems.   My current position as a Manufacturing Engineer for new products allows me to design new processes, evaluate new equipment and develop manufacturing capabilities.

Coordinated projects, ordering or approving orders for materials, performing document & drawing generation and control, scheduling personnel & materials, and provide technical support and guidance.

 

Highlights:

·  Design and development of Cam & Crank Sensor Test Stand for Hall Effect sensors and VR sensors.  This was used by and for profiling GM< Ford & Chrysler sensors.  LASER measurements (500 kHz dual receiver LASER with accuracy to 2 microns) and Optical  sensors, for proximity, growth & Jitter.

 

·  Worked on and designed exciters (CDI) for Jet engines.  As well as designed an Inductor and Transformer used by NASA.  I had some experience with failure analysis (NASA) of a transformer that had been in space (and back) 3 or 4 times before it failed.
 

·  High-side switch circuit design for the Canadian Army 24V to 48V at 125 Amps.  This required a voltage multiplier to reduce switch loses and make the use of a low R_ds ON MOSFET as the switch.

 

·  Batteries:  I’ve experimented with photovoltaic cells and kept up with the technology but more specifically I currently use and/or to specify all types of batteries for test equipment, Lab top computers, cell phones and toys which includes Ni-Cad, Ni-H2, Li-Ion.

 

·  First Dual negative voltage Ignition coil for the 5.7L Hemi Engine.

 

 

·  AC/DC: Simple laminated transformer for step down and regulation controller through feedback into an OP-AMP, feedback voltage direct through

 

·  DC/DC: 5W to 50W with switching frequencies 1kHz (self-oscillating Flyback) to 125 kHz PWM. With transformer and Inductor designs for use in PWM with switching frequencies up to 1 GHz.  Power budget analysis experience has been related to power consumption and efficiencies.

 

·  Worked with (Maxim) IC manufacture to integrate 1 transformer and 2 Buck/Boost Inductor designs i into IC's, as well as a 12Vdc to 185Vac for back-light panel (EL/LCD) (purpose to sell a transformer design.

 

·  CDI's 1 Joule to 100 Joule (development tool for
Garrett) and a 125 Amp High side switch.

 

·  Design & developed exciter test machine (Unit) sold as a commercial test unit.  Pressure leak testing, Voltage stress and full electrical functional testing.

 

·  PWM's for life testing Ignition coils, power converter in an IGBT w/ diagnostics,  12Vdc to 250Vdc (Flyback), buck boost design to convert alternator voltage to 250 Vdc and CD used in ION sense circuit.
 

Accomplishments:

Provided one employer with the ability to manufacture transformers in-house, by purchasing the equipment, supplying the training and technical support.

Built Test Fixtures, Test Equipment and Designed Test Procedures to support production.  One piece of Test Equipment became a new product with a unit-selling price of $60k.

With knowledge acquired in the area of Gas Discharge Theory, I was instrumental in the reduction of scraped Spark Gaps, resulting a cost saving of $20k per month.

Recent Patent on Switch mode control using Magnetic Field sensing.

Designed & Developed Magnetic components for a Semiconductor Manufacturer, which was, integrated into IC’s, this resulted in a new customer a gross sales of over $1M a year.

Successfully assisted manufacturing facilities, in Mexico, St Kitts, Puerto Rico, Central America (Costa Rico & Honduras), India and Asia (Maylasisa & China), in problem solving new product launch and manufacturing issues, through effective communication and team building.

Worked with core supplier to develop a method of control to Stress aneal  Nanocrystalline cores at a fourth of the typical cost and at high of the tolerance shift.

Developed a thermally conductive potting material, which saved more than 35 lbs per 787-8 airplane and improved the thermal performance of the magnetics.

Co-developed, with Epoxy Dispensing Company, automated epoxy vacuum dispensing equipment and established it in production.  Allowing the plant site to reduce touch time, improve repeatability and provide a void free potting.  This is now a standard product for that manufacture.

Worked with a Winding machine manufacture to develop a 3 phase transformer winding machine.  Installed, trained and validated the equipment into Puerto Rico production line.

Developed the fusion crimping process that used to bound (fuse) mechanically strippable magnet wire into a lug without pre-stripping the insulation, which save time and reduces F.O.D./.
