| Abstract: | A palm-size power supply system for thermo-electrically cooled Si-PIN detector was designed and introduced.High density circuit topologic and Surface Mount Devices(SMD) are used,so that little dimension,small weight,high efficiency, high stability,low ripple noise and low cost should be achieved.A detector,model XR-100CR,can be powered with the inside rechargeable battery for more than 7 hours.The system can be widely adopted in various In-Situ X-ray fluorescence spectrometry based on Si-PIN detector.Idea about a temperature controlled power supply for thermo-electrical cooler and its realization,and techniques for transformerless high voltage bias with low noise and high stability are discussed as well. |
