Abstract
To enhance the competitive edge of the material cost, IP(Integrated Power) Board form of inverter circuit is widely used in large area LCD TV(Greater than or equal to 40 in.). This scheme is Two Stage System and one inverter drives multi-lamp in a parallel circuit. This paper analyzes the conventional IP Board inverter controlled with Pulse Width Modulation (PWM), and its problems such as serious hard switching and excessive circulating energy can be solved by a proposed Pulse Count Modulation (PCM) scheme. To confirm the validity and superiority of the proposed system, theoretical analysis and experimental results are presented.
