本論文研製之多級多相全橋逆變器的硬體設計，藉由隔離變壓器與光耦合手段，提供高可靠度之十一階的動力模組，此逆變器由兩個主要部份所構成：1. 驅動板驅動電路負責動力模組的驅動。2. 功率板電路板之直流鏈電容與電流偵測電路，負責穩定電源與偵測馬達電流及全橋MOSFET功率輸出電路。這兩部份的設計都密切關係到整個逆變器的動力輸出與性能。

A procedure in this paper, the hardware design of Implementation and drive of the multi-level multi-phase cascaded H-bridge inverter is developed. By means of isolation of transformer and optocoupler, the power module of high reliability is provided. The inverter consists of two main parts Constitute: 1. Driver board drive circuit is responsible for driving the power module. 2. DC link capacitor and current detection circuit of the power board circuit board, is responsible for stabilizing the power supply and detection motor current and H-bridge MOSFET power output circuit. These two parts of the design are closely related to the entire inverter power output and performance.
