3.1.2. Bi-Directional Half-Bridge and Full-Bridge Controlled Converter

In Figure 11, the circuit diagram of a bi-directional half-bridge and full-bridge controlled converter is given. In the bidirectional half-bridge-controlled converter, the AC energy received from the electricity grid is converted into DC energy in half-bridge with the switching elements and is reduced to the voltage level of the battery by using the converter (buck converter). At the same time, the DC received from the battery is amplified by the boost converter circuit, which increases the voltage and then gives it to the grid by converting it from DC to AC through diodes [78]. In the bidirectional full-bridge-controlled converter, the conversion process from AC to DC is done through a full-bridge converter circuit. The other parts are the same as the bidirectional half-bridge-controlled converter [78,79].
