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