Anyone has an idea on how to test layer insulation within a winding on foil wound delta-wye transformer (115VAC, 400Hz) . The test will serve as an isolation and verification for shorts (latent that can not be discovered during functional testing) across layers test were interlayer winding is...

Yes, that is what happening.

I Hope this will clarify things better. The square wave is really symmetrical on the + and - side with slight dead time applied between the + and - portion. The amplitude will change between +/- 11 and +/- 15V based on other factors and the DC will be altered to keep a fixed rms value of the...

It is going to be a reference DC signal that will be used by the PWM to set the duty cycle.

The quasi-weaveform has a fixed frequency of 60hz but it is going to be a duty cycle controlled based on the amplitude.

Any ideas on how to convert +/- 10V quasi-square waveform to DC (for pwm control) without using RMS to DC chips. 5% accuracy will do. Thanks

I would like to control MOSFET rise and fall time to 100us without using the gate resistor as a mean of control (due to gate capacitance tol.). I am using the a half-bridge circuit to switch +/-100 VDC at 15 ohm load for 10 ms on and 10 ms off. Any suggestions? Thanks
