The presented ballast consists of a discontinuous‐conduction‐mode operated dual‐boost converter to achieve input current shaping, and a high‐frequency combined with a low‐frequency square‐wave‐driven half‐bridge‐type inverter for supplying the HID lamp with low‐frequency square‐wave sources. The attractive features of the proposed ballast are high‐power factor (> 0.99), low total harmonic distortion of input utility‐line current (< 10%), high efficiency (> 90%), cost‐effectiveness and freedom from acoustic resonance. The operational principles, design guidelines and a design example are included in this paper. A prototype ballast circuit has been successfully implemented and tested for supplying three different brands of 70W HID lamps operating with 110 V‐root‐mean‐square input utility‐line voltage. Satisfactory experimental results demonstrate the functionalities of the proposed ballast.
