Modular braking adjuster with hybrid design

A modular braking adjuster, comprising:

• a brake resistor and at least two submodules, wherein the brake resistor and the at least two submodules are connected to form a series circuit, wherein at least one submodule is constructed as a full-bridge module and at least one submodule is embodied as a double half-bridge module, and
• a control device configured to
• generate a voltage across the serially connected submodules, with the voltage composed of a direct voltage component and an alternating voltage component,
• to control with the direct voltage component by open-loop control or closed-loop control power to be converted into heat by the modular braking adjuster,
• to control an amplitude of the alternating voltage component by open-loop control or closed-loop control in such a way that the energy taken up by the modular braking adjuster averaged over time is converted into heat in the brake resistor, wherein the amplitude of the alternating voltage component is at least temporarily greater than the direct voltage component, and
• to at least temporarily generate a negative proportion of the current through the modular braking adjuster for maintaining an energy balance.
