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.

Claim (Index 34):
The converter according to  claim 32 , wherein the control module is configured to determine the upper limit W Lmaxu \u03a3  for the internal energy stored in the capacitors of the submodules of an upper arm of the converter by means of the function: W Lmaxu \u03a3 = C tot 2 \ue89e ( NV smMax ) 2 - W ru \u03a3 \ue8a0 ( t r ) where C tot  is the sum of the capacitances of the capacitors in the arm, V smMax  is the maximum voltage that is acceptable in a submodule, N is the number of submodules in the arm, and where t r  is a determined instant at which the internal energy in the arm reaches the upper limit W Lmaxu \u03a3 , with this instant being obtained by the formula: t r = 1 \u03c9 \ue89e ( cos - 1 ( - 2 \ue89e I diff I g ) - \u03b8 ) + 2 \ue89e k \ue89e \ue89e \u03c0 \u03c9
