Inverter cct for bipolar voltage pulses - has transformer control switch for magnetic storage used for automatic primary voltage polarity reversal

摘要

The inverter circuit is intended for generating alternating voltage and bipolar voltage from direct voltage and comprises a transformer having at least one primary and one secondary, the primary side being connected via a controlled switching element to at least one direct voltage source. The transformer core stores magnetic energy during the period that the controlled switching element connects the primary of the transformer to the direct voltage source, and this stored energy causes automatic reversal of the transformer primary voltage after the controlled switching element is shut off. A diode is provided to maintain the continuous flow of the magnetising current in the circuit.
