PWM technology is the most widely applied in contravariant circuit and is also the core of frequency conversion technology. Meanwhile it also plays an important role in machine tool, hydraulic pressure location control system and other mechanisms. PWM技术在逆变电路中的应用最为广泛,也是变频技术的核心,同时在机床,液压位置控制系统等机械装置中也发挥着重要的作用。
