چکیده

This paper describes the development of high voltage power supply for electro-optics applications. The power supply consists of MOSFET driver, voltage multiplier circuit and voltage controller. A single timer 555 generates 1.3 kHz square pulse to drive the power MOSFET that connected to a standard step up transformer. By using voltage multiplier technique, the output from secondary transformer was step-up. The variable DC high voltage output is produced up to 4 kV. The input voltage as low as 12 volt is required to generate smooth and stable high voltage output.

Reduction of Switched Mode Power Supply Electro‐Magnetic Emissions in Automotive Cockpit Applications by Using of a Field Programmable Gate Array to Implement Pseudo Random Spread Spectrum Modulation

Introduction At the heart of automotive design is the requirement to pass Electro-Magnetic Compatibility (EMC) limits, by minimising conducted and radiated emissions and susceptibility. The use of Switched Mode Power Supplies (SMPS) is now common-place, yet a prime source of electro-magnetic emissions. Minimising these emissions is a key goal of SMPS design. Use of spread spectrum techniques is...
