30+ years experience in system development and engineering team management specializing in off line SMPS, inverter, lighting ballast/driver and motor drive design. Circuit and system design/development/verification including; circuit and magnetics design, digital control/embedded firmware, component and system definition and application support. Effective problem solver accustomed to working very closely and developing relationships with customers to support design-in activity. My current role includes taking the lead in technical discussions and ongoing engagement with key accounts working with internal marketing and sales. I am an experienced team manager of engineers and technicians at various levels designing and developing electronic systems for power supply, motor drive and lighting applications.I have worked at system level as well designing several analog ICs from initial conception/definition to final release working individually and as part of a team.Specialties: Definition and design of switching power supplies and inverters, including high and low voltage CCM and DCM Flyback converters, forward, push-pull and bridge topologies, PFC, resonant half-bridge converters, synchronous rectification, ranging from a few Watts to kWs.Dimming and non-dimming electronic ballast and converter design for fluorescent, HID, Halogen and LED light sources; ASIC design and definition for above applications.Analog, digital and high voltage electronic system design. High voltage analog IC design (circuit design, simulation and layout using Cadence). Firmware development with assembler (mostly Microchip PIC) and C programming for micro controllers and DSP in various applications including DMX512 and DALI controls. System analysis, debugging, problem solving. Technical writing: Application notes, technical articles, technical trainingSchematic capture, simulation and PCB layout tools: Altium, Protel, Orcad, Simetrix, PSPICE.
