About SP

The invention relates to a pulse technique and can be used to create power supply units for frequency lasers and other electrical devices with a pulse power takeoff from the supply network.

The purpose of the invention is to stabilize the current consumed.

Fig. 1 shows an electrical block diagram of the device; figure 2 - timing charts of the device.

The storage capacitor charge device contains an inverter 1,

the first rectifier 2, the inputs of which are connected to the output of the first inductive-capacitive converter (IEP) 3, and the outputs are connected to the first and second output buses 4 and 5, the second rectifier 6, the second inductive capacitor: bone converter (IEP) 7 , capacitor 1, voltage regulator 9 and, voltage regulator 9 is connected between the first inductive-capacitive converter 3 and the inverter 1, between the first and second inputs of which is connected, respectively, the first and second plates of the capacitor 9 - R Without the second inductive-capacitive converter 7 with the first output of the second rectifier 6, the second output of which is connected to the second plate of the capacitor 8, the control input

The second inductive-capacitive converter 7 is connected to the output of the voltage regulator 9.

The device works as follows.

Rectifier 6 rectifies the alternating voltage of the power supply (Fig. 2a) and through IEP 7, this voltage is applied to the capacitor 8 and to the input of the inverter 1 (Fig. 26). In inverter 1, the upper voltage is converted to an alternating high frequency (Fig. 2b) and fed to a stabilizer 9, from whose output (Fig. 2d) it is fed to the inputs of the first and second IEP 3 and 7.

The output voltage of the biaspizator 9 voltage is controlled in proportion to the frequency of the charge-discharge cycles of the load capacitor, so that at any frequency it does not consume extra power from the network.

Thus, at each frequency of the charge-discharge cycles of the storage capacitor, the magnitude of the output voltage of the stabilizer 9, and hence the current consumed by the device from the mains, has a well-defined specific value. IEP 3 (fig.2d) through the rectifier 2 charges the storage capacitor (fig.2e) with a stable current, and IEP 7 maintains a stable current value of the inverter 1. After the charging capacitor terminates during the pause required to discharge the storage capacitor load, and the pause between the end of the charge cycle and the start of the discharge, the necessary dp completion of transients in the charge circuit, the energy consumption of the storage capacitor is absent, but the current consumed by the inverter from the supply mains remains Formerly, since IEP 7, by increasing its output voltage, keeps this current unchanged.

In this case, the input voltage of the IEP 7 does not change, since it is stabilized by the voltage stabilizer 9.

Increasing the output voltage of the IEP 7 increases the voltage on the capacitor 8, i.e. The mains power consumed by the storage capacitor is stored in the capacitor 8 during the pause.

After the end of the pause at the beginning of the new charge cycle, the storage capacitor begins to consume energy, which leads to a decrease in the output voltage of the IEP 7. The capacitor 8 transfers the stored energy to the storage capacitor and the voltage on it decreases to the set value. In the following, all processes are repeated.
