The aim of this paper is to propose a high-power- factor (HPF) single-stage inductor-capacitor-capacitor (LCC) res- onant inverter for liquid crystal display (LCD) backlight. A half-bridge LCC resonant inverter shares switches with a power- factor-correction circuit to form single stage. The proposed single- stage LCC resonant inverter can achieve almost unity power factor and ripple-free input current by using a coupled inductor, and can also realize zero-voltage-switching by operating the switches above the resonant frequency. Thus, the proposed single-stage inverter not only provides HPF to the utility line, but also achieves circuit simplicity, low cost, and high reliability. Experimental results on a 32-in LCD backlight are obtained to show the performance of the proposed inverter.
