    Transformer Interlayer Isolation

    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...

    Simple square waveform to DC converter

    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

    Mosfet switching time

    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
