摘要
为满足磁悬浮轴承的控制需要,采用移相的方法成功设计了一个较大功率的三态开关型功率放大器,理论分析和实验都充分证明这种三态开关型功率放大器相对于普通的两态功率放大器具有电流纹波小,功率器件损耗小,电磁干扰小等一系列优点。
To meet the needs of magnetic suspension bearing＇s control, has designed a biggish power tristate switching power amplifier by use of the phase - shift method. Theory analysis and experiments prove that such tristate power amplifier have a series of advantages agaist ordinary double - state power amplifier, such as little current wave, small power devices loss and slight electromagnetic interference etc.
