FIELD: transforming equipment engineering, possible use in power sources for inductive heaters.
SUBSTANCE: method for launching current inverter, containing rectifying cells, generating direct and reverse current semi-waves in load includes generation and injection of launch control impulses to rectifying cells, generating direct and reverse current semi-waves on load, starting from the launch signal injection moment, measuring launch control impulses, generating and turn by turn injecting of main control impulses to rectifying cells, generating direct and reverse current semi-waves in load. Voltage level is set. Voltage level at input of current inverter is measured. Voltage level at input of current inverter is compared to given voltage level. Launch signal is injected when voltage level at input of current inverter exceeds given voltage level. First and second temporal intervals are given. Launch control impulses are injected simultaneously to rectifying cells, generating direct and reverse current semi-waves on load. On expiration of the first time interval, launching control impulses are measured on rectifying cells, generating direct current semi-wave on load. On expiration of second time interval, launch control impulses are measured on rectifying cells, generating reverse current semi-wave on load. Generated further are main control impulses, which are then injected to rectifying cells, generating direct and reverse current semi-waves on load.
EFFECT: expanded area of application of method for launching parallel current inverter with self-excitation working on two-operation rectifying cells.
