Abstract
The present invention discloses a converter with cold start-up and a cold start-up method for modular power converters that allows converter operation tests to be carried out without a connection to the AC grid. For that purpose, the control module powers the power converter modules, disconnects the power converter from the AC grid, selects a power converter module as the AC-source module and configures a voltage and a frequency for the AC-source module, selects the power for the other power converter modules and sets starting conditions. Previously, the control module is powered by an AC source that can be internal or external, such as an uninterruptible power supply (UPS) or a DC source (photovoltaic field), via a DC-AC transformer.
