FIELD: electronic engineering. ^ SUBSTANCE: one-phased bridge transistor inverter is disclosed with transformer load and capacitor, enabled serially with primary winding of transformer in diagonal line of alternating current of transistor bridge, bridged by reverse diode bridge. For achieving technical effect, one-polar transistor key is utilized, enabled between connection point of primary winding of transformer with capacitor and common point of two additional reverse diodes, not connected to diagonals of alternating current, transistor bridge. One-polar key is controlled by logical circuit AND of optical-electronic type, providing control over inertial state of transistor bridge. ^ EFFECT: protection from resonance overvoltages in the network. ^ 3 dwg |
