PARKER派克调压阀AU200-8 1/4具体方法如后所述。单极性SPWM法(1)调制波和载波：曲线①是正弦调制波，其周期决定于需要的调频比kf，振幅值决定于ku,曲线②是采用等腰三角波的载波，其周期决定于载波频率，振幅不变，等于ku=1时正弦调制波的振幅值，每半周期内所有三角波的极性均相同(即单极性)。调制波和载波的交点，决定了SPWM脉冲系列的宽度和脉冲音的间隔宽度，每半周期内的脉冲系列也是单极性的。(2)单极性调制的工作特点：每半个周期内，逆变桥同一桥臂的两个逆变器件中，只有一个器件按脉冲系列的规律时通时通时断地工作，另一个完全截止；而在另半个周期内，两个器件的工况正好相反，流经负载ZL的便是正、负交替的交变电流。双极性SPWM法(1)调制波和载波：调制波仍为正弦波。

PARKER派克电磁阀PHS510P-6-24V-L 1/8当时，国内鼠笼型异步电动机一般采用直接启动，或用自耦、星三角启动器启动。上世纪九十年代，以单片机为核心、半导体可控硅为执行元件的智能化电机软启动器进入市场，并在2000年以后开始加速发展，目前市场规模约为20亿。软启动器主要解决电动机启动时对电网的冲击和启动后旁路接触器工作的问题，对电机有较好的保护作用，在轻载情况下可以实现一定程度的节能（约5%），但是节能效果远远不如变频器。随着变频器产业的崛起，并因此使变频器的价格大幅下降，近几年来，变频器才又逐渐取代了软启动器的作用。变频器的国产化进程正在快速崛起，质量稳定性进步很快，加上服务和成本上的优势，变频调速的性价比高，质量和价格的竞争优势越来越明显。
