DC-DC converter device
The invention consists in one converter device switching DC-DC with a limitation circuit of in-rush electric current and relative DC-DC conversion process. DC-DC converters are important in mobile electronic devices. They often contain several sub-circuits, requiring different voltage level from that supplied by the battery. DC-DC converters offer a method of generating different voltage levels controlled by a variable voltage battery.
This innovation concerns of a isolated converter device switching DC-DC boost with a power transformer composed by: primary winding and secondary winding with central socket; a reactive circuit connected in series between the socket and a node to which a continuous input voltage to be converted is applied (in particular a battery voltage); switching net with devices to selectively connecting half-windings of the secondary winding to a fixed voltage reference (in particular a mass reference) behind the control of respective switching driver signals; a circuit for limiting a inrush current in the reactive circuit.
- Mobile electronic devices powered by batteries (phones, laptop);
- Automotive (electric vehicles, hybrid vehicles).
- Electrical voltage level control;
- Less space occupied;
- Bidirectional converter;
- Cheaper than other converters;
- In-rush current limitation during the starting of the converter.
