Abstract: The present invention generally relates to a technique for constructing a large-capacity audio amplifier by connecting a series of Class D amplifiers in parallel. In particular, the present invention relates to a parallel connection type Class D amplifier configured to suppress a circulating current by reversely connecting a coupled inductor therebetween when a series of Class D amplifiers are connected in parallel. According to the present invention, when a series of Class D amplifiers are connected in parallel and driven, circulating current (DC bias current) can be suppressed, and thus Class D amplifiers can be used in high-quality and large-capacity fields. In addition, according to the present invention, there is an advantage of high operational flexibility in that a series of Class D amplifiers can be selectively driven in parallel or independently driven individually through switching settings. In addition, according to the present invention, since circulating current removal is achieved through a coupled inductor device without using a control method such as current control, system efficiency is high.
