Abstract
The invention relates to a modular multilevel converter (10) including a control module (12) for regulating the internal energy stored in the capacitors of the submodules of an arm of the converter, the control module being suitable for limiting the internal energy to below an upper limit and/or to above a lower limit, by using parameters measured on the DC power supply network (110) and on the AC power supply network (120) together with setpoints for the operating power of the converter.
