Ref. no. | Inverter topology | Strengths | Weaknesses |
|
[200] | 1 − ϕ half-bridge inverter | The switch count is reduced and it is quite inexpensive | The harmonic content of the output voltage is high |
[201] | 1 − ϕ full bridge inverter | Preferably for high voltage systems | Quite high harmonic content |
[205] | 3 − ϕ full bridge inverter | Smooth control and cheap | stress is higher, resulting in electromagnetic interference |
[206] | 3 − ϕ four-leg inverter | The DC-link capacitor balancing problem does not exist | Additionally, two more switches are required |
[207] | 3 − ϕ six switch inverter | The requirement for power semiconductor devices is less, with simple topology | Compensation for unbalanced voltages is difficult |
[208] | 3 − ϕ split capacitor six switches four-wire inverter | Able to compensate for unbalanced voltages | DC-link capacitor balancing will face input/output voltage ratio issues |
[203] | AC-AC converter | Variable and constant energy sources are not required | Lower efficiency for heavy sag in the substandard grid |
[204] | Z-source inverter | Capable to supply the voltage for lower DC-link during deep voltage sag | A number of LC elements are required and shoot through the problem |
