Abstract
A direct current to asymmetrical square wave alternating current converter is provided that includes two direct current supplies A and B, that provide, respectively, VA and VB output voltages; and four commuting devices (Q1, Q2, Q3 and Q4); in that the power supplies and the commuters form a bridge structure of, at least two Half-bridge substructures, each of which includes two commuting devices and, at least, a direct current power supply. The Half-bridge substructures are connected to each other in the intermediate and low branches, where the work charge RL is connected in the intermediate branch.

A direct current to asymmetrical square wave alternating current converter comprising:
- two direct current supplies A and B, that provide, respectively, VA and VB output voltages;
- and;
- four commuting devices (Q1, Q2, Q3 and Q4), the two direct current supplies A and B and the four commuting devices form a bridge structure comprising at least two Half-bridge substructures, each of which includes two of the commuting devices and at least one of the direct current power supplies A and B, the Half-bridge substructures being connected to each other in intermediate and low branches and configured to produce a work charge RL in the intermediate branch,
- in a first state of the bridge structure, a first two (Q1 and Q3) of the commuting devices are closed to produce the work charge with voltage supplied by direct current supply A,
- in a second state of the bridge structure, a second two (Q1 and Q4) of the commuting devices are closed to produce the work charge with voltage supplied by direct power supply B,
- in a third state of the bridge structure, a third two (Q3 and Q4) of the commuting devices are closed with no work charge being produced.
