| How Does a Multiplier Work? |
|
|
|
The most commonly used multiplier circuit is the
Half-Wave Series Multiplier. All multiplier circuits
can be derived from its operating principles. The
following description assumes no losses and represents
sequential reversals of polarity of the transformer Ts in
Figure 1. (in reality several cycles are required to
reach full voltage): |
 |
| 1) Ts=Negative Peak: | C1 charges through D1 to Epk |
| 2) Ts=Positive Peak: | Epk of Ts adds arithmetically to existing potential C1, thus C2 charges to 2Epk thru D2 |
| 3) Ts=Negative Peak: | C3 is charged to 2Epk through D3 |
| 4) Ts=Positive Peak: | C4 is charged to 2Epk through D4 then Epk(N) where N = number of stages. |
