Suppression of the mode conversion of inverter noise caused by an asymmetric boost converter circuit

Abstract (in Japanese) (See Japanese page) 
(in English) An asymmetry circuit causes impedance unbalance, leading to mode conversion. Especially, in the case of a power conversion circuit, a reactor is usually on the one side of the positive and negative electrodes. So, a power conversion circuit with a reactor causes mode conversion in most cases. If we try to reduce noise generated by mode conversion with a noise filter, we should add some components, or need a larger noise filter. We can solve this problem by impedance balancing to suppress mode conversion. However, we need to understand the mechanism of the mode conversion of an asymmetric power conversion circuit with a reactor to balance the impedance. In this paper, we clarify the mechanism of the mode conversion of an asymmetric power conversion circuit with a reactor, and suggest new method to suppress the mode conversion with a simple change of the circuit．
