<P>PROBLEM TO BE SOLVED: To reduce noise which accompanies fast switching of a power converter having a switching element and severely hinders loss reduction of the power converter because increase of dv/dt in order to reduce element loss generates noise with higher and larger power. <P>SOLUTION: A voltage-type power converter with a pulse width modulation reduces high-frequency noise by connecting a DC midpoint potential of the power converter and a load output point via a capacitor. <P>COPYRIGHT: (C)2012,JPO&INPIT |
