POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/105968
Kind Code:
A1
Abstract:
In a dual active bridge (DAB) converter, a control circuit 13 has: a first operation mode that performs control so as to include a transmission state in which a first bridge circuit 11 energizes a first DC part and a primary winding n1 of an insulated transformer TR1, and a second bridge circuit 12 energizes a secondary winding n2 of the insulated transformer TR1 together with second DC parts E2, Cb, and a commutation state in which both ends of the primary winding n1 are short circuited in the first bridge circuit 11, and the second bridge circuit 12 energizes the secondary winding n2 together with the secondary DC parts; a second operation mode that performs control so as to include the transmission state and an accumulation state in which the first bridge circuit energizes the primary winding together with the DC part, and both ends of the secondary wiring are short circuited in the second bridge circuit; and a third operation mode that performs control so as to include the transmission state, accumulation state, and commutation state.
