Antisaturation control for x-ray generator inverter.

摘要

An inverter provides alternating current to the high-voltage transformer by way of alternating the current flow through its diagonals. Means are provided to sense the current flow in the transformer primary to obtain an indication of an impending saturating condition and for correcting such an imbalance by selectively unbalancing the current flow in the respective diagonals to correct the condition. The sawtooth generator is used to unbalance the alternate half-cycles in response to an integrated signal from the current-sensing means to thereby control the inverter output to provide an unbalanced diagonal flow until the condition is corrected.
