Abstract

The invention relates to a pulse technique, in particular to devices for charging storage capacitors. Nel of the invention is an increase in efficiency while reducing the charge time of the capacitor. 11, a diode 12 and new connections have been introduced, which allows using the secondary winding of the HP transformer not only to charge the storage capacitor, but also to control the transistor key. 2 Il.

Description

connected through a cumulative condensate Q value, which is to regulate the spacing 7 and the resistor 11 to the anode of the second diode 10, the cathode of which is connected to the anode of the additional diode 1.

As a control circuit 5, a resistor, a potentiometer, a current generator made on a transistor, etc. can be used.

The device works as follows.

When a power source is connected to pins 4 and 6, transistor switch 1 is opened by current flowing through control circuit 5. At the same time through the collector winding 2 transformer40

Displacement current control circuit 5 control. The trapezoidal shape of the accumulation current increases the average power of the device, which leads to a reduction in the accumulation wake up time. KI NDENSATOR 7.
