摘要
讨论了一种新型的集成脉冲宽度调制开关功率放大器SA60,并与分立元器件开关功放进行了比较,设计了适用于主动磁轴承功放电路,进行了单自由度调试实验。
A new type of power amplifier:SA60,which is an integrated pulse width modulate (PWM) switching power amplifier,is studied.Moreover it is compared with the discrete components switching power amplifier.A power amplifier circuit which applies to active magnetic bearing (AMB) was designed and was experimented in the debugging of singlefreedomdegree.
