Abstract.A novel topology, Current-Sourcing Push-pull Parallel-Resonance Inverter (CS-PPRI) was investigated theoretically and experimentally. The proposed power stage is built around a current fed push-pull inverter. The main features of the proposed inverter is a load independent output current and Zero Voltage Switching (ZVS). It I s suggested that the proposed CS-PPRI is a vlable alternative for realizing electronic ballasts for low and high intensity discharge lamps.
A b s t r a c t -The practicality of designing a fixedfrequency resonant Inverter that Is controlled by a variable inductor was investigated theoretically and experimentally. The proposed approach was studied by considering the design of a current-sourcing resonant inverter. The theoretical analysis yielded a closed form (albeit implicit) relationships between the inductance and the transfer function of the inverter. Excellent agreement was found between model predictions and experimental results. An experimental inverter was designed and tested as an electronic ballast for high pressure discharge lamp (Metal Halide lamp). The inverter was operated at 200 kHz and included an ignition circuitry and a dimming capability.
