MEASURING TRANSFORMER AND METHOD OF CONTROLLING MEASURING TRANSFORMER Russian patent published in 2014 - IPC H02M7/483 H02M7/515 H02M7/527 H02M7/53846 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering. The converter comprises control units (3), which are respectively connected to one of multiple sources (2) of input voltage. Each control unit (3) varies input voltage (U_IN1, U_IN2, U_IN3, U_IN4) supplied from the connected input voltage source (2) and applies an intermediate voltage (U₁, U₂, U₃, U₄). The converter comprises switching elements (41), wherein potentials (V₀, V₁, V₂, V₃, V₄) of intermediate voltages, determined by the intermediate voltages (U₁, U₂, U₃, U₄), are applied across each switching element (41) and each switching element (41) selects one of the potentials (V₀, V₁, V₂, V₃, V₄) of intermediate voltage to output as the corresponding potential (V_OUT1, V_OUT2, V_OUT3) of output voltage. The method of using such a converter comprises the following steps: setting up the control units (3) such that the control units (3) apply potentials of intermediate voltages comprising the applied potentials (V_OUT1, V_OUT2, V_OUT3) of output voltages; setting up the switching elements (41) such that one of the potentials (V₀, V₁, V₂, V₃, V₄) of intermediate voltage is selected and applied across the corresponding output (A₁, A₂, A₃).

EFFECT: invention can be used in inverters to apply multiple output voltages or multiple potentials of output voltages to corresponding outputs.
