Michael Schutten
EMC Consultant for Power Electronics
Michael Schutten is presently self-employed as an EMC consultant, specializing in using novel technologies to ensure EMI compliance for power converters and inverters, ranging from low power up to several megawatts. He has developed many innovative technologies to diagnose, locate, and resolve EMI problems.
He was previously a Principal Engineer at the General Electric Global Research Center in Niskayuna, New York. While there he developed advanced EMC technologies that enabled compact, EMI compliant power electronic systems. He has developed robust and ultra-low noise power converters for military, industrial, and consumer applications.
His areas of expertise include electromagnetic compatibility, power electronics, RF electronics, nonlinear control theory, and analog electronics. He has taught multiple short courses at universities, government laboratories, and at twelve IEEE EMC and power electronics conferences. Mike has 35 issued patents and multiple journal and conference papers.
John Stanford
