Abstract

A transformerless zero-voltage switching (ZVS) megahertz interleaved inverter is proposed in this paper to improve the driving efficiency of dielectric barrier discharge (DBD) lamps. The proposed inverter consists of two inductors and two metal oxide semiconductor field effect transistors (MOSFETs). The MOSFETs operate in the interleaving mode and the energy injected into the DBD device is controlled by adjusting the turn-on time or frequency of the switching devices. Various waveforms can be realized by controlling the phase difference of the pulses. The operational principles were analyzed and the circuit was simulated. A prototype was built and demonstrated. Experiment results show that the proposed inverter can achieve ZVS and generate high-voltage bipolar pulses with a frequency range from several kilohertz to 1 MHz. A short pulse with a steep rise time of 40 ns, a peak-to-peak voltage of 1400 V and full width at half the maximum of 220 ns at a frequency of 1 MHz can be achieved. The lamp efficiency was increased by more than 7% when compared with the lamp driven at kilohertz. Therefore, it is suggested that the proposed inverter is suitable for driving the dielectric barrier discharge lamps efficiently with a simple structure.
