| Abstract |
In this paper a Zero-Current-Switching (ZCS) class E-amplifier is proposed as fluorescent lamp ballast. The ZCS-class E-amplifier features lower voltage stress accross the switch than the Zero-Voltage-Switching (ZVS) class E amplifier. This is an important advantage which allow to supply the circuit from the American main voltage (Vac = 120 V), maintaining only one switch for the ballast. The operation and characteristics of the ZCS class E amplifier as electronic balast are analysed in this paper. The presented study includes selection of the more suitable resonant tank, power factor correction using the "modified valley fill" technique and parametric analysis of the ZCS class E amplifier. |
