SYSTEM FOR COUPLING AT LEAST ONE AC POWER SOURCE TO A CONTROLLABLE ENERGY STORE AND ASSOCIATED OPERATIONAL METHOD

摘要

The invention relates to a system for coupling at least one AC power source (9) to a controllable energy store (2) which is used for controlling and supplying electric power to an n-phase electric machine (1), where n =1. Said controllable energy store (2) comprises n parallel power supply branches (3-1, 3-2, 3-3) which can be connected to a reference bus (T-) and to respectively one phase (U, V, W) of the electric machine (1). At least one n-phase AC power source (9) can be coupled to the individual power storage branches (3-1, 3-2, 3-3).
