President
Carl Belnap
Mr. Belnap founded Design Criteria, Inc. in 1999 as an innovative, power electronics design and manufacturing firm. He has a broad range of experience in power supply and magnetic design.
Mr. Belnap was responsible for the design and manufacture of a low noise power controller to shut down 120A of 8V power in less than 5 µseconds as well as several low power, off-line double ended forward converters for military applications. His magnetics designs reduced radiated emissions in the forward converters.
Carl has designed a 1000A inductor and many other custom magnetics, both planar and conventional, including a miniature transformer that was embedded in an eight pin dip and BGA integrated circuit (IC). He has also developed a self oscillating low voltage power supply with 2500 V isolation and a very low component count.
Through his innovative skills a 1 MHz power transformer for DC-DC converter applications was designed in which the power density is more the thirty times the state-of-the-art. Mr. Belnap was responsible for the development of a very fast switching, high efficient, 300V, 60A, solid-state power controller and current limiting power controller for a NASA space application and a 25 W, 10 KVDC DC-DC converter for an industrial application.
He designed the EMI filter for a 2500 W uninterruptible power supply (UPS) and oversaw the EMI testing. Mr. Belnap has designed several magnetic components for EMI filtering. Mr. Belnap also designed and marketed a remote weight monitoring system.
