PUSH-AND-PULL INVERTER Russian patent published in 2008 - IPC H02M7/5383 

FIELD: electricity.

SUBSTANCE: result is achieved by implementation of two resistor dividers of voltage and two current stabilisers in push-and-pull inverter. For this purpose, two voltage regulator diodes and three resistors are introduced, one of the said resistors being current sensor for two current stabilisers and current limiter at the same time. The said introductions allow for keeping equal magnification current in both inverter sides enabling eliminating of the main push-and-pull inverter drawback such as over-magnification asymmetry, increasing specific power of the proposed inverter, improving transistor switch switching over dynamics, reducing current bump amplitude and, as a result, reducing heating and likelihood of transistor switches disruption. Thus, reliable operation of the said push-and pull inverter within wide range of supplied voltage is ensured.

EFFECT: elimination of over-magnification asymmetry and increase in specific power and reliability.
