Abstract
This conversion system for converting electric energy is intended to be connected to a load, and includes the connection terminals, that are capable of being connected to the load, an electric energy converter, and a filter including at least one capacitor. This conversion system for converting electric energy additionally also includes a switching module configured in order to switch between a first configuration in which the filter is connected between the converter and the connection terminals and a second configuration in which the converter is connected directly to the connection terminals, with the filter being bypassed.
Claims8
A conversion system for converting electric energy, the conversion system for converting electric energy comprising:
- connection terminals configured to be connected to a load;
- an electric energy converter;
- a filter comprising at least one capacitor;
- a switching module configured to switch between a first configuration in which the filter is connected between the electric energy converter and the connection terminals and a second configuration in which the electric energy converter is connected to the connection terminals, with the filter being bypassed, the switching module including a first switch connected in series with the filter, and a second switch connected in parallel with the filter and with the first switch connected in series, the first switch being closed in the first configuration and open in the second configuration, and the second switch being open in the first configuration and closed in the second configuration;
- and
- a protection diode connected between the electric energy converter and the connection terminals, the protection diode being configured to protect back flow of current from the load to the electric energy converter,
- wherein the filter is configured to reduce oscillations in voltage delivered to the load.
