The flying capacitor inverter combines low semiconductor costs and gives a multi-level output with high output frequency and low dynamic losses. Although the input is only two level with no need for the enormous DC-link capacitor bank, the output is multi-level and the output frequency is a multiple of the switching frequency.
I have a Firestar (Voltronic from what I can work out) 3000VA 24V inverter that someone kindly connected 48v batteries to. They popped the main capacitors on the inverter. There are 4 of them. They are 4200uf 35V electrolytic caps, which are not available locally as far as I can find.
Within the operation of the three level flying capacitor inverter four different modes can be derived. During normal operation the voltage of the flying capacitor is half of the output voltage and the inductor current is continuous.
Grid tie inverters require filter components in two key areas: The DC bus and AC output. The AC output filter is a low pass filter (LPF) that blocks high frequency PWM currents generated by the inverter. Three phase inductors and capacitors form the low pass filters.
The demand for highly efficient solar inverters is steadily increasing in recent years. However, more cost efficient solutions are also desirable. Multi-level inverters are commonly used in PV applications.
In flying capacitor inverter topologies the commutation loops include capacitors. A capacitor from the commutation point of view can be considered zero impedance. Its main role in the commutation loop is to offset the two outer semiconductors from each other.
