Abstract: The increased demand of an intermediate storage of electrical energy in battery systems, in particular due to use of renewable energy, has resulted in the need of dual active bridge converters or bidirectional DC to DC power converters. The most cost effective solution for electrical energy storage is battery.
The most cost effective solution for electrical energy storage is battery. The battery output is converted to AC for connecting to electrical loads. Charging and discharging of the battery can be carried out by bidirectional power converters.
The isolated shifting full-bridge converter suitable for medium and large power applications is a DC-DC converter that can operate in two quadrants. The application of the bidirectional DC/DC converter can greatly reduce the size, weight and cost of the system where energy bidirectional flow is required [ 4 ].
The output of the current loop acts as a modulation signal, and the closed-loop control of the system is realized by a pulse width modulation circuit, a phase shift circuit and an isolation drive circuit.
