高力率コンバータを活用したPAM形インバータシステム PAM Inverter System with Power Factor Corrected Converter
In most cases, PWM power factor corrected (PFC) converters are constructed by a diode rectifier and an active power circuit such as a boost or buck-boost chopper. Besides the PFC operation, the active power circuit can control the dc output voltage. The output voltage of the PAM inverters are controlled by varying the level of dc input voltage. A PAM method reduces the voltage and current stresses of the inverter and motors.<br>This paper proposes a new PAM inverter system with high power factor converter to obtain a sinusoidal input current. A Proposed PAM method to reduce the torque ripple in the induction motor can be reduced a switching losses by providing a pausing interval where the switching operation stops during a part of one period.
