HIGH-VOLTAGE DC-TO-DC CONVERTER Russian patent published in 2018 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: high-voltage converter includes a primary key (K) formed by a normally closed key element (J1) connected in series with the normally open key element (M1) provided with a control circuit (G2), a load (Z1), connected in series with the primary key (K), the primary key and the load (Z1) are intended to be connected to the poles of the DC voltage source (E). The voltage source (Vp), which can be used to control (K), is obtained by connecting the main peak detector circuit (DC) at the middle point (K), and the point is referred to as (A). The supply of the power control circuit (G2) of the normally open key element (M1) can be made by DC voltage (Vp), which makes the device, in general, with autonomous power supply. The main peak detection circuit (DC) additionally includes an optional unidirectional current key (Dj), connected on one side to the node (B) between the storage (C1) of electrical energy and the unidirectional current key (D1), and on the other side - to the secondary winding.

EFFECT: increase the efficiency through the use of a system with a cut-off and implementation of start at very low input voltage.
