	NOIZGON Phone: 408-663-9130 Email NOIZGON www.noizgon.com/	The operation is shaky. There is jitter. You have a huge overshoot. The waveforms are not like in the simulation. You do not pass EMI. It seems that you have a severe noise problem going in the control. There are some solutions but most are dealing with the packaging. The physical implementation of power circuits is extremely critical. Unfortunately, low noise packaging is not taught in ME schooling. This background skill is not widespread. It comes from experience. NOIZGON will help to solve the design implementation problems. We can put you back on schedule. There are several possible fixes. We can teach your EEs and MEs how to do a Noise - Gone design. Our latest achievement is a PWM power transfer above 200 KW. The waveforms are textbook green clean. There is no more Red.
