“…To avoid or effectively eliminate acoustic resonance, supplying the HID lamp with a low-frequency, square-wave source is the most favourable method utilised in commercial electronic ballasts [6, [14][15][16][17][18][19][20][21][22][23]. In addition, an electronic ballast for HID lamps with power-factor-correction (PFC) function is generally required to comply with regulations such as the IEC 61000-3-2 Class C standards.…”

This study presents a single-stage electronic ballast for the high-intensity-discharge (HID) lamp with high-power factor. 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 highpower factor (> 0.99), low total harmonic distortion of input utility-line current (< 10%), high efficiency (> 90%), costeffectiveness 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.
