POWER SWITCHING DEVICE AND CONTROL METHOD OF POWER SWITCHING DEVICE Russian patent published in 2020 - IPC H03K17/82 

FIELD: power switching devices.

SUBSTANCE: disclosed is a power switching device (1) which includes buffer circuit (3), filter circuit (4), transformer (5), recovery circuit (9), matching circuit (10) and power switch (13). Buffer circuit (3) provides output voltage (V_b) depending on input voltage (V_in) and control voltage (VG). Filtering circuit (4) blocks the constant component of the buffer output voltage (V_b), which is added to the secondary side of transformer (5) by restoring circuit (9). Power switch (16) is controlled by unipolar conditioned voltage (V_D), which is provided by restoring circuit (9) for supply to matching circuit (10).

EFFECT: design of a power switching device made as an automatically configurable module.
