Significant reduction of emission is possible with PWM frequency modulation scheme. A forward converter is used to verify the effectiveness of the scheme. A guidance of parameter selection for noise reduction is given.v, 68 leavesBTDapplication/pdfenIn CopyrightLD5655.V855 1992.L54Electromagnetic interferenceElectromagnetic noise -- AnalysisFrequency modulation detectorsThesishttp://scholar.lib.vt.edu/theses/available/etd-08222009-040339/
