FIELD: electricity.SUBSTANCE: converter assembly comprises bidirectional non-insulated DC voltage converter (2), DC voltage converter (3) with galvanic insulation between input and output and control system, low-voltage accumulator battery (5), common high-voltage DC link (6), at least one converter coupled to AC machine, at least two controlled switches (4) and control system. The control system is designed so that controlled switches (4) are closed at transmission of energy by bidirectional non-insulated DC voltage converter (2) in direction from its input up to its output and open at of energy in reverse direction.EFFECT: ensuring effective bidirectional conversion of energy and insulation of circuits related to accumulator battery from DC link in the transmission mode from DC link to the accumulator battery.16 cl, 8 dwg |
