INVERTER INSTALLATION AND METHOD FOR INVERTER INSTALLATION CONTROL METHOD Russian patent published in 2014 - IPC H02P27/08 H02P21/00 H02P6/16 

FIELD: electricity.

SUBSTANCE: inverter installation includes basically an inverter (3), a component (12, 26, 27) for rotation rate detection and a control component (9). The inverter (3) comprises plurality of pairs of switching elements (Q1-Q6). The control component (9) controls on-off state of the switching elements (Q1-Q6) to convert direct current from the direct-current power source (1) to alternating current performing the first and second controls in sequence when rotation rate of the engine (4) coupled to the switching elements is more than the specified rotation rate. The first control switches on the switching elements (Q1, Q3, Q5), which are connected directly to the positive electrode of the power supply source and switches off the switching elements (Q2, Q4, Q6), which are connected directly to the negative electrode of the power supply source. The second control switches on the switching elements (Q2, Q4, Q6), which are connected directly to the negative electrode and switches off the switching elements (Q1, Q3, Q5), which are connected directly to the positive electrode.

EFFECT: increased service life of the switching elements.
