Design of switching Power supply for Xerox's new generation of copiers (more than $10 M of business). This design was for highly competitive market with multinational safety and EMC requirements with international manufacturing facilities. The design included:A 2 kW power supply with 7 different outputs using off-line 20 kHz switching technology.1 kW power supply with 5 outputs similar to the first (this was the first switching power supply used by Xerox). 200 w off-line switching power supply, single-ended forward converters used in low-end copiers.High voltage, high frequency power supply for ion charging.Power system for Xerox's next generation of high-quality small copiers. This was a multi-discipline design. It included computers, mechanical and Xerographic techniques. Led a team of Engineers, Technicians and Product Designers and was later responsible for the manufacturing of the above products.
