Patent number: 10302542Abstract: In a particulate detection system (10), a control board (911), a high voltage generation board (913) and an isolation transformer (720) are respectively disposed in a first space (921d) and a second space (921e) separated from each other by an inner case (923). When electromagnetic noise is generated in the high voltage generation board (913) and the isolation transformer (720); specifically, at the primary winding of the isolation transformer 720, at the time of switching the primary current supply, the electromagnetic noise is blocked by the inner case (923). This configuration reduces the influence of electromagnetic noise generated in the primary winding on the control board (911).Type: GrantFiled: May 18, 2017Date of Patent: May 28, 2019Assignee: NGK SPARK PLUG CO., LTD.Inventors: Hidekazu Minami, Kaoru Hisada
