Abstract:
In this paper soft switching technique is employed for a bidirectional non-isolated DC-DC converter. For turn on Zero-Voltage Switching (ZVS) technique is applied for turn off and Zero-Current Switching (ZCS) technique is implemented. Input voltage (VL ) acts as source in step-up mode. High output gain is attained as a result of current flow from source to load. If VL acts as load that is when the current flow reverses the output voltage gain is low. When hard switching technique is used the switching loss increases and more heat is dissipated. Therefore in this technique, life span of switches is improved by less heat loss and the output voltage can be increased. The converter plans to reduce the switching current and also improves voltage gain when compared to the conventional bidirectional converters. It uses an intermediate switching pattern to carry out seamless mode change.
