Characteristics of a low EMI noise inverter using resonant dc link circuit

摘要

Recent developments in electronics apparatus design, consisting in the reduction of operating voltage of their LSI components to lower their energy consumption, result, in principle, in a diminished immunity of electronic devices to electromagnetic interference(EMI). Therefore, since the suppression of EMI generated by such peripheral devices as, for example, uninterruptible power sources providing power to such electronic apparatus has become an impor- tant topic of research, we decided to investigate low-noise inverter circuits in which a resonant power converter circuit technology and soft switching techniques are used.
