One small addition: let me clarify some terminology we used in this thread: Inverter: basically transforms one AC or DC voltage, into another AC voltage of same or different frequency. Therefore, AC-AC or DC-AC. Inverters are often used in cars, to produce 220V AC from battery power. Converter: DC to DC or AC to DC (switched). The PSU in the PC and many other devices are actually converters. Most of the time people simply call them switched-mode power supplies or switching power supplies. Rectifiers: AC to DC without voltage reduction. If you look at the schematics I've sent, the bridge (4 diodes) plus the first big electrolite capacitor form a rectifier. Obviously, it's pretty simple to make rectifiers. Disclaimer: this terminology might have changed recently to reflect other devices, in which case I apologize. Of course, power diodes are also called rectifiers. Voltage multipliers: they create high DC voltage from an AC source. Someone posted a simple schematic for a one-stage voltage multiplier in this thread. The cascade in TVs and monitors are realized with voltage multipliers. Used also in lasers, air ionizers etc. Here's a typical voltage multiplier schematic: http://www.voltagemultipliers.com/html/multwork.html cheers mario Message was sent through the cbm-hackers mailing list
