摘要
The authors describe an electronic ballast design with the capability of low radiated and conducted EMI over a wide dimming range, It overcomes some limitations of traditional electronic ballasts that use frequency variation for dimming control, The proposed design allows soft switching of the ballast from full-power operation down to less than 10% power. Low-cost and low-voltage power metal oxide semiconductor held effect transmitters (MOS-FETs) can be used in the proposed dimmable electronic ballast. The design approach is described and implemented successfully in a 2 x 36 W fluorescent lamp system.
