PD Converters and Water Usage
For Dry Campers Only No secret I've been a fan of PD converters for 15 yrs or more, and for more than one reason. The PD maintains my batteries every day of the year, except for the 4-5 months that...

All converters have:
1. a peak charge circuit (diode & capacitor) front end that converts ac to 170Vpeak dc.
2. a transformer that drops the 170Vdc to usable levels.
3. a pwm controller (and power fets) that controls transformer switching to achieve the desired output voltage.
4. diodes & inductor/capacitor filter at transformer output to convert pwm waveform to a dc level.
The regulated output voltage is:
Vout = Vpc * Np/Ns * pwm
Where:
Vpc is the peak charge voltage
Np is the number of primary turns on the transformer
Ns are the turns on the secondary
pwm is the percent duty cycle of the controller

Where do I find one of these dc transformers you're talking about in item 2. I been around a while, and I've never seen one of these.
