Description

one

The invention relates to the field of pulsed radio engineering and can be used in electric-spark installations and other devices where energy is required in the storage co-capacitor.

The well-known ycTipo cTBO charge of a storage capacitor, containing a constant-current power source, a chain of series-connected droplets and a storage capacitor, is shunted by a diode in reverse connection, and the dosing co-selector has a low efficiency

The purpose of the image is to improve the efficiency. devices.

For this, the chip is connected to the "lemmas of the DC power source through the bridge on controlled vents, and the dosing to the dvsato; p is included in the diagonal of the bridge.

At FIG. 1 shows the scheme of the proposed device; FIG. 2 - graphs of voltages and currents in different parts of the circuit.

The device contains a power source that is connected to "Lemmas 1 TL 2, a chain of series-connected Drossel 3 and capacitor 4, a diode 5 connected in the opposite direction.

The choke 3 and (the capacitor 4 is connected to the terminal m. 1 and 2 through a bridge consisting of controlled valves 6, 7, 8, 9. The metering capacitor 10 is included in the diagonal of the bridge.

The principle of operation of the device is as follows. At the initial time o, when the voltage across the capacitors is 10 volts. 4 is equal to zero, the first pair of controlled ventilation openers opens, for example, 6 to 9. At the same time, an oscillatory charge of constant 10 and 4 occurs.

On the other hand, ti (cf. FEG. 2), when the voltage of the capacitor 10 reaches the value (power supply source, the diode 5 "current through the capacitor 10 is interrupted. The energy accumulated in the inductor 3 is transferred to the capacitor 4, then the circuit is ready for the next switch. At time 4

control valves 7 and 5 are turned on and oscillatory recharge of capacitor 10 occurs up to the voltage of the power source (in the opposite direction).

At the end of the charge, the energy stored in the choke 3 is transferred to the capacitor 4 through the diode 5. Then the processes are repeated.

Thus, energy is transmitted to each half-cycle to the storage capacitor 4.
