Abstract:
    A pure AC voltage-current inverter of precise low noise type is prepared as carrying out stopping treatment on input voltage by stopping circuit then coupling said voltage to positive and negative inverters, generating two precise output currents with reversed polarities by symmetric constant current circuit and using them as bias currents of two said inverters being used to covert input AC voltage to be AC current, superposing AC current with constant bias current to obtain general output current, superposing output currents of two said inverters to counterbalance constant current component for obtaining pure AC output current.
