Abstract
The present invention relates to an electrical converter for power supply, which is constructed from individual modules. Each of the identical modules includes a module capacitor and can be switched by switching elements such that the module capacitors of the modules may be connected in series or in parallel, or a current flow takes place through the modules without charging or discharging the module capacitor. In this manner, the voltage can be connected across the terminals of the converter by a corresponding control of the switching elements in stages with low loss levels. According to the invention, the voltages of these capacitors are adjusted with respect to each other by load balancing prior to parallel connection of the capacitor modules so that the corresponding losses are minimized.
