Abstract
The subject of the invention is a voltage step-down converter with an extended range of obtained stepped-down output voltages, comprising a capacitive input divider which constitutes a branch of three capacitors (1), (2) and (3) connected in series, connected between a positive input terminal (10) and a negative input terminal (11), wherein a negative output of the capacitor (1) included in the input capacitor divider connected to the negative input terminal (11) of supply voltage UIN and to an output of a controlled switch (5), whose output is connected to a negative output terminal (13) of stepped-down output voltage and to a negative input of an output capacitor (39), as well as to an input of a controlled switch (7) and to an anode of a diode (4). A positive input of the capacitor (3) is connected to the positive input terminal (10) of the supply voltage UIN and to an input of a controlled switch (6), whose output is connected to an input of a choke (18) and to an output of a controlled bidirectional switch (8) and to a cathode of a diode (9), whereas an output of the choke (18) is connected to a positive input of the output capacitor (39) and to a positive output terminal (12) of the stepped-down output voltage. Whereas to a connection point of the capacitors (2) and (3), a cathode of the diode (4) and an input of the controlled bidirectional switch (8) are connected, and to a connection point of the capacitors (1) and (2), an anode of the diode (9) and an output of the controlled bidirectional switch (7) are connected.
