Comparison of Circulating Current and Non-circulating Current Modes

1. |
Reactors are required to limit the circulating current. These |
Reactors are not required for normal operation but sometimes may have |
2. |
Losses increase due to circulating current and hence efficiency |
Efficiency is higher. |
3. |
The converter current is due to presence of circulating current. |
Converter current can be discontinuous. |
4. |
Less response time, therefore fast response. |
Response time is more so slow response. |
5. |
Transfer characteristics are linear. |
Transfer characteristics is nonlinear due to discontinuous current. |
6. |
The fault circulating current, due to undesired firing of converters |
Simultaneous firing of both the converter due to faulty signals will |
7. |
The converter current is higher than the load current, due to circulating |
The converter current is the same as output current. |
