标准电流等级 - The standard current controlled bi - state pwm switching power amplifier has its intrinsic deficiencies , such as significant harmonic distortion and restriction of the dynamic characteristic , which have serious negative effects on the magnetic bearing system
传统的磁轴承开关功放大都采用电流两态调制技术，存在电流纹波大、动态特性受限等缺点。 - Become a kind of new electronics circuit - current - mode circuit . it is replacing the traditional design method of the voltage - mode in the high frequency high - speed signal processing realm 。 this thesis mainly discussed the modified second - generation current conveyors based on the current - mode kinds of new cuicuit components , they are stronger modified standard current - mode parts in fuctions on this foundation . mainly including the modified differential difference current conveyor ( mddccii ) 、 the fully balanced second generation current conveyor ( fbccii ) 、 ( full balances ) four - terminal floating nullor ( fbftfn ) and the current differencing buffered amplifier ( cdba ) , they are all function very strong standard current - mode parts , they all can provide some circuit functions of better than general operation amplifier , because they have the voltage importation and the current importation , therefore use it since can carry out the voltage - mode signal processing circuit expediently , can also carry out the current - mode signal processing circuit expediently , and have to increase the benefit bandwidth to accumulate more widely than the voltage - mode , but have their advantages more according to the current - mode filter of the modified current conveyor , because it constitutes in brief , the filter wave function is stronger and they are better than in general use operation amplifier of many advantages , be easy to composing for example 、 high speed 、 frequency bandwidth 、 the power supply voltage requests low 、 consume small , the impedance is different from etc . advantages , otherwise they have biggish dynamic range , and flexible circuit synthesize , so they are the best active parts
