Abstract：Focused on multi-order high frequency resonant converter for electrodeless lamp, this paper expounds operating principle and steady-state characteristics, leading to key issues of load matching. When starting up, electrodeless lamp needs high trigger voltage for its large equivalent resistance. Lamp resistance suddenly decreases as soon as it lit up. The converter outputs maximum power and zero voltage switching is realized in steady state. From these aspects, theoretical analysis and mathematical deduction are carried on. Matching scheme suitable for electrodeless lamp load characteristics and the design of key parameters are obtained taking into full account the features of electrodelss lamp at different operating stages. Based on the proposed design method, a laboratory prototype adapts to different working conditions has been built. Experimental results were proposed to confirm validity and effectiveness of the scheme presented.
