ASTABLE SINGLE-PHASE CONVERTER Russian patent published in 2014 - IPC H02M3/137 

FIELD: electricity.

SUBSTANCE: device relates to the field of pulse equipment and is designed to convert DC voltage. The objective of the invention is to increase efficiency of an astable single-phase converter. The device comprises a switching key VT1, a comparison device DA1, a CMOS inverter, the first divider R3, R4 and the second divider R1, R2. The resistor R2 is current-setting. The switching key VT1 via an inductance coil L1 is connected between terminals of the primary source GB, and the inlet of the second divider is connected to the source of shift U_sh, which may be the primary source GB. Terminals of supply of the CMOS inverter DD1 are connected to the same source. Intervals of inductance coil charge and discharge time in this device are determined by the inductance coil itself.

EFFECT: invention provides several advantages in respect to available devices, including highest limit efficiency factor at pulse power supply to passive loads, possibility to ensure stable mode without OOS and independence of output capacity on the value of used inductance.
