This paper presents the analysis and implementation of a low-cost high frequency inverter for driving a nonlinear load. The proposed high frequency inverter utilizes the structure of a switching power amplifier circuit that is very simple and highly efficient. The proposed inverter can drive a nonlinear load such as a cold-cathode fluorescent lamp. The drive circuit of the proposed inverter is operated by a clock generator circuit and a comparator. In this paper, the circuit of the proposed inverter is introduced, the operational principle is analyzed, and a prototype implementation is discussed. Experimental results using a cold-cathode fluorescent lamp demonstrate the performance and characteristics of the proposed inverter for driving a nonlinear load.
