Abstract
This paper describes a novel high frequency induction heating system to reduce particulate matters (PM) exhausted from diesel engine. In the first place, the optimum structure of a metal filter which traps PM is investigated. Secondly, ZCS characteristics of the multi-resonant ZCS high frequency inverter as the power supply of the high frequency induction heating system are analyzed in relation to load equivalent circuit. On the basis of the analysis, the high frequency high power supply with high efficiency for induction heating system has been estimated by experimental results in the treatment of diesel engine generator.
