STATIC TRANSDUCER Russian patent published in 2023 - IPC H02M5/44 H02J9/06 

FIELD: electrical engineering.

SUBSTANCE: static transducers for powering consumers of three-phase alternating current. In the proposed static transducer, designed for uninterrupted power supply of AC consumers, there are two power sources - a three-phase AC power source as the main source and a battery as a backup. The essence of the proposed static transducer is to use n chokes (n≥1), which make it possible to eliminate the redundancy of chokes for low-power static transducers and ensure the formation of a constant voltage at the output of the booster circuit in a wide power range, in increasing the efficiency of work by connecting a constant reference voltage through the diode to the output of the booster circuit, which is always present and does not affect its operation, but allows to provide a stable voltage at the output within the specified limits in case of failures in the operation of the AC voltage source and the appearance of “dips” in the voltage values at its outputs.

EFFECT: providing a stable voltage at the output of the booster circuit within the specified limits when switching contacts to make and break in galvanic isolation contactors between the power circuits of an AC voltage source and the power circuits of a DC source in the form of a storage battery. A reduction of pulses, improving the stabilization of the output voltage and improving the weight and size indicators.
