摘要

Taking-an-STC-microcontroller-chip-as-control-chip-,this-article-elaborates-on-the-design-and-development-in-hardware-and-software-of-off-grid-inverter-apply-to-the-photovoltaic-experiment-.-Firstly-,-hardware-design-is-made-,including-the-inverter-circuit-,dead-circuit-,power-circuit-,isolated-driving-circuit-,-output-filter-circuit-.Next-,software-design-is-made-,including-the-preparation-and-debugging-program-.Finally-,-the-inverter-is-successfully-debugged-in-the-photovoltaic-experiment-.%以STC单片机为主控芯片，阐述了用于光伏实验台的离网逆变器的软硬件设计及调试；描述了硬件设计，包括逆变电路、死区电路、电源电路、隔离驱动电路、输出滤波电路等；完成了软件设计，包括程序的编制与调试；最后将逆变器在光伏实验台上成功调试。
