Title:
BIDIRECTIONAL POWER CONVERTER CIRCUIT
Document Type and Number:
Japanese Patent JPS57183267
Kind Code:
A
Abstract:
PURPOSE:To communicate electric power while converting at the prescribed voltage rate between DC power sources by respectively connecting switching circuits to the coils of a transformer in which coils are reversely coupled. CONSTITUTION:When an electric power is delivered from a DC power source 4 to a DC power source 5, a switching circuit 2 is driven by a driving circuit 6, an energy is stored in a transformer 2, a current flows through the power source 5 when the circuit 2 is OFF, and the pewer source 5 is charged. When an electric power is delivered from the power source 5 to the power source 4, the power source 4 is charged from the power source 5 through a switching circuit 3, a transformer 1 and the circuit 2. Thus, the electric power is delivered from the power sources 4, 5 of the side driven at the switches 2, 3, thereby enabling the transmission of the electric power in both directions.
