Circuit diagram of a capacitive power supply: The vector diagram makes it clear: The majority of the input voltage drops out at the reactance of the capacitor with virtually no power dissipation being created in the capacitor. As the capacitor is directly connected to the power supply, very high demands are made on its reliability.
CONNECTING THE UNIT Disconnect the wires of your existing system from the transformer and connect them to the output of the CDU. Connect the input of the CDU to the transformer. The system is now ready for operation. See the completed wiring diagram for the connections to the capacitor discharge unit.

A good rule of thumb to estimate the time it takes to discharge the capacitor is to calculate the time constant of the RC network of the 5τ capacitor and resistor. After = 5 · R · C = 5 · Rbleed · Cin we expect the voltage at the capacitor to be 99% lower than the initial voltage at the start of discharge.
Capacitor Discharge Units (CDU's) supply a high current 'burst' to the solenoid. This current burst is over by the time the switch contacts open, thus eliminating back emf across the switch contacts, Should a solenoid be left in circuit, the current flowing through it (after the initial surge) will be less than 50mA.

Both the standard power and high power CDU may be operated from any AC voltage up to 24 volts ing a high voltage increases the power from a CDU. Operating from 24 volts instead of 12 volts gives 4 times the power. (24 volts can be obtained by connecting two 12 volt transformer windings in series). Generally a voltage of around 16 Volts AC is used to power the CDU. The …
We then short-circuit this series combination by closing the switch. As soon as the capacitor is short-circuited, it starts discharging. Let us assume, the voltage of the capacitor at fully charged condition is V volt. As …
The CDI ignition circuit produces a spark from an ignition coil by discharging a capacitor across the primary of the coil. A 2uF capacitor is charged to about 340 volts and the discharge is controlled by an SCR. A Schmitt trigger oscillator (74C14) and MOSFET (IRF510) are used to drive the low voltage side of a small (120/12 volt) power transformer and a voltage doubler …
The Capacitor Discharge Unit MkII circuit diagram. We have called it CDU-2 to identify it separately from our Capacitor Discharge Unit also available from the author. Both these kits are available and the only difference is CDU-1 uses a 2N 3055 transistor and CDU-2 uses a BD 679 Darlington transistor.
But for solenoid point motors to operate effectively, a Capacitor Discharge Unit (CDU) is recommended to provide sufficient kick to fire the motor! Solenoid Point Motor. A solenoid (magnetic coil) point motor uses two solenoids connected to a suitable power supply to pull a pin towards them. This pin is attached to the tie bar and throws it in ...

If you are using a DC power supply, these are not required and will drop the output voltage by another 1.5 if included. AC power input - 16 Volts AC is great - should be preferred, though. Diodes should be rated 50PIV (peak inverse voltage) …
A capacitive power supply circuit is basically an electrical system that utilizes a capacitor as an intermediary between a specific source of power and its final destination. As the capacitor charges and discharges, it sends electrical current through the system. This current is then supplied to the intended destination—whether that''s ...
