of the diode, the secondary winding of the transformer 12 through the recovery heat exchanger 18 is connected to the positive and common buses of the constant voltage source 1, respectively, the third winding of the transformer 12 is connected to the storage capacitor 11, the constant current source 1 Shunt the fourth capacitor 15.

The device works as follows.

When the thyristor 7 is switched on, the charge of the drossels 3 starts from the positive bus of the source 1 drossel 3, diode 9, the thyristor 7 and the common bus of the source 1. The capacitor 2 is charged along the circuit: the positive bus of the source 1 choke 4, the diode 10, the thyristor 8, the common bus source 1 with the polarity indicated without brackets.

When the first capacitor 2 is charged, the second thyristor 8 is opened. At the same time, the capacitor 2 closes the thyristor 7 and recharges along the circuit: the thyristor 8, the capacitor 15, the choke 3 and the diode 9.
