摘要：

Physical processes occurring upon turning-on of the transistor in a converter stage with a saturable-core choke, placed in the clamping diode's circuit, are analyzed. The period of the diode's charge removal and the energy lost in the transistor in various turn-on modes are determined. It is shown that the use of the saturable-core choke can be expected to reduce the energy loss by half or more.
