subject: Rectifier Bulb? HoHoHo

RS>  True, but the voltage is too high to be

RS> you use the bridge as you have suggested.

TW>  I am getting Confused. Who in their Right Mind would replace the Two
TW> Diodes with a Bridge.

 I would, if I had one on hand or if it
were cheaper than individual diodes,
plus it is often easier to connect to.

TW> And How can one say it would be a doubling
TW> Circult. You are Putting in Twice to voltage required for a Bridge
TW> Rectifier circuit. OF course the Output would be Doubled. BUT that has
TW> Nothing to do with the Rectifier Doubiling Voltage.
TW> And incidently How many rembember the "Real" Voltage Doubling
TW> Rectifier Circuit used in some old Transformerless Circuits??
TW> There was as I recall even a trick to make a Voltage Quadrupiling
TW> circuit.

 It is not a voltage doubler, except when
used with a center-tapped transformer (and
that transformer center-tap is used). You
have either a + and a - 15 Volts and/or a
30 Volt supply - double the voltage of
using only two diodes with that same basic
circuit.

 There are voltage doublers, triplers,
quadruplers, etc. Just look at many TV and
monitor HV sections.
