REACTOR-CAPACITOR FILTER FOR DIRECT CURRENT SOURCE

摘要

The invention pertains to electrical engineering, particularly to DC-DC converters. There is proposed a reactor-capacitor filter for DC source with the reactor in circuit of the DC source and capacitor at output of filter. The switches of inverter, which is connected to the output of said filter, are incorporated in a single-phase bridge mode. The output of inverter through transformer and rectifier is connected to load, and the diagonal pairs of switches of inverter are activated periodically and contrary by signals generated in control junction. For purpose of improvement the functional properties of converter, a diode is introduced in series with the capacitor in conductivity direction of DC source, and a transistor is connected in parallel and in reverse direction of conductivity of DC source. A control gate of said transistor through driver is connected to output of AND-NOT logical gate but two inputs of the gate are connected to signal outputs of the control system for switching one leg of the inverter with contrary activated transistors.
