摘要
The aim of this paper is to incorporate the analysis of component tolerance in the design criteria of resonant inverters applied to the control of high-pressure sodium (HPS) lamps. This method may also be considered for metal halide (MH) lamps. The design accepts a large load variation without exceeding the lamp power limits given by the standard. The analysis is focused on the selection of the most suitable value of the resonant network in order to achieve a good repeatability of the circuit performance. The study is based on the analysis of the lamp power sensitivity regarding the lamp aging and the tolerance of the circuit components. The proposed design is validated with experimental results and a statistical study by the Monte Carlo method.
