POWER-SUPPLY SOURCE CIRCUIT Russian patent published in 2014 - IPC H02M3/145 H02M3/158 H05B37/02 

FIELD: electricity.

SUBSTANCE: invention pertains to the field of electrical engineering and can be used in (1) a power supply source. The power-supply source circuit contains: input contacts (17, 19) intended for connection of the power-supply source circuit (1) to the direct-current energy source circuit (7), two output contacts intended for connection of the load circuit (11) the power-supply source circuit (1), a bridge circuit (3) containing at least two in-series switches (M₁, M₂) interconnected between two output contacts, a resonant circuit (5) connected at its one end to one or more input contacts and at its other end to the interconnecting track (15) of at least two switches (M₁, M₂) of the bridge circuit (3) and at least two diodes (D₁, D₂), at that the first diode (D₁) is coupled between the first input contact intended to connect a positive contact of the direct-current energy source (7) and the first end contact of the in-series switches. The first end contact is connected to the first output contact, the second diode (D₂) is coupled between the input contact intended for connection to a negative contact of the energy source circuit (7) and the second end contact of the in-series switches, at that the second end contact is connected to the second output contact.

EFFECT: increasing supply voltage.
