摘要：
The circuit comprises:
a low-voltage supply (V B ),
a storage inductor (L₁) interposed between one pole (1) of the supply (V B ) and the load (L i ),
a first electronic switch (SW₁) in parallel with the load (L i ),
a second electronic switch (SW i ) in series with the load (L i ), between the load (L i ) and the other pole (2) of the supply (V B ),
a third electronic switch (SW₃) interposed between the first pole (1) of the supply (V B ) and the junction (N) between the load (L i ) and the second switch (SW i ), and
an electronic control unit (ECU) arranged to pilot the switches (SW₁, SW i , SW₃) in a predetermined manner.
