Solar energy low pressure sodium lamp electron ballast development - 51RD Chinese electronic net
Sunday, April 12th, 2009 at 09:42 | No commentsCategories: Power SupplyShort Content: Abstract: Based on low pressure sodium lamp (LPS) and the solar energy power supply's characteristic, has developed the 55W new solar energy low pressure sodium lamp electron ballast. The system structure was simple, uses the reliable LC series resonance starting circuit, the overflow, has pressed with the protection circuit is exceptionally complete, finally has given the experimental result and the experiment sample.Key word: Low pressure sodium lamp; Solar energy; Electronic town class clamour; LC series resonance 0 introductions The solar ... -
In electronic ballast power factor compensating circuit’s analysis and application - 51RD Chinese electronic net
Saturday, February 14th, 2009 at 00:02 | No commentsCategories: Power SupplyShort Content: Abstract: IR2166/IR2167 is collection power factor adjuster (PFC), the ballast and half bridge driver is a body's new electronic ballast driving circuit. The internal power factor adjusts the (PFC) electric circuit by the critical breakover pattern (CCM) work, may obtain the high power factor, the low total harmonic distortion (THD) and the DC voltage adjustment. Gave the model PFC control circuit's principle and has carried on the analysis.Key word: Ballast; IR2166; IR2167; Power factor adjustment 1 introduction Traditional ... -
Uses in small fluorescent lamp’s 25W the mini ballast
Monday, January 26th, 2009 at 15:53 | No commentsCategories: Power SupplyTags: Ballast, fluorescent lampShort Content: The fluorescent lamp is one kind (lumens per watt) has the white light most inexpensive method by the least electrical energy consumption. Now, the small fluorescent lamp's every year sale scale reaches several billions, but also unceasingly enhances to the fluorescent lamp reliable request. Present's lighting system needs the ballast control function to actuate the small fluorescent lamp, but increased the cost and the design time like this, moreover these ballast control function must act according to each different type ... -
