电源转换电路经常被应用在马达驱动器或可再生能源的功率转换上,设计中包括可以将直流电压转换为交流电压的电源转换器,以便用来推动马达或连接到可再生能源系统的电网(图1)。电源转换器的核心是以高频率运作,能够承受高直流电压、价格昂贵的功率组件,例如IGBT,这些功率组件提供的效率与可靠度是系统发挥最大化效能的关键。光耦合器通常被应用在这类系统中来提供控制电路 Power conversion circuits are often used in motor drives or in the conversion of renewable energy sources, including power converters that convert DC to AC voltage to power the motor or the grid connected to a renewable energy system 1). The heart of power converters is high-frequency operation, capable of withstanding high DC voltages and expensive power components such as IGBTs. The efficiency and reliability offered by these power components are the key to maximizing system performance. Optocouplers are commonly used in such systems to provide control circuitry
