FIELD: non-destructive testing.
SUBSTANCE: calibrated voltages of maximum value corresponding to the maximum variation of one of the physical parameters are applied to the outputs of the coils of the matrix converter. The calibrated voltage is modulated simultaneously by the sum of calibrated voltages of the permissible values. The voltages are applied continuously until the corresponding converter output failure. The time period from the beginning of the voltage apply to the failure is recognized as total service life of the matrix converter to be tested.
EFFECT: enhanced accuracy of determining.
