Virtual Four Pole Power Supply
Click to

The V4P power supply board is mainly intended for driving multi-channel ZapPulse based amplifiers, like
Home Cinema installations, from 4 channels up to 8 channels.

| If you only need two channels we recommend the smaller (and cheaper) Predator supply as a better
match. |

Features
- 100.000uF Low Impedance capacitors, connected in a V4P network.
- Ultra Fast Recovery (25 ns) rectifiers
- Soft Start Circuit
- DC Filter (prevents transformer hum).
- On Board Gate Driver Regulator.
- One Module Does it All
The principle of Virtual Four Pole Networks
Here you can see the principle of V4P networking capacitors. All caps are synchronously charged or
discharged, and
none of the caps exchange charge currents. Every capacitors equivalent series resistance is about 100
milliohms, but the
combined series resistance to the neighbour capacitor is about 200 milliohms. So no capacitor can
exchange currents with the others.

All necessary functions are combined on the module, so virtually no wiring is called for.

| The 8 Ultra Fast rectifiers are placed on small separate heat sinks. In front of the picture you see the Soft Start relay,
which enforces a slow cut into the mains grid, avoiding stress to the rectifiers, switches and capacitor | |
banks.
The
big black capacitor in front of the picture is a DC blocking cap, it prevents DC components of the mains
grid to
reach the primary winding of the main transformer that would cause it to hum.

The wiring to the modules is very simple. Note, we have removed one capacitor from the ZapPulse module on
this picture, to give you a better
view of the wiring.
We recommend transformers of 2 X 42 V AC secondary, at 400-500VA to drive 4 ZapPulse modules, and the doubles
for 5 to 8 channels.
