switcher duty cycle - high or low?
The LT app note is probably referring to subharmonic oscillation present in power supplies with current mode PWM controllers and with duty greater than 50%. Voltage mode controllers do not have this problem. However, current mode controllers have a single pole response in the line and control to...- rwstowe

High Power water capacitors
I agree with CarlPugh about using water for capacitor dielectric applications. Even deionized water resistivity is poor compared to the resistivity of capacitor oil. So, for any high voltage application except for short uS pulses with very low duty, the resulting power dissipation would quickly...- rwstowe

High Power water capacitors
Hello fusion2022, Thank you for your question. Without knowing the specifics of your application, is deionized water a possibility? Deionized water, as the name suggests, is water with ions stripped out of it by a continual filtration process such as a bed of resin beads. A company like...- rwstowe
