This article proposes a modular switched-capacitor inverter which employs a single dc source. The inverter can gen-erate seven-level and obtain triple voltage gain. Moreover, the maximum voltage stress on switches can be kept within 2Vdc due to the elimination of H-bridge.
In [15 - 17], a multi-level inverter named “coupled three-phase converter” is presented, with ten power switches in its structure. This inverter cannot cover all the switching states necessary to create the five-level line voltage. This limitation will reduce the inverter's flexibility and increase the THD in the output voltages.
Switched capacitor inverters are low cost and compact and are capable of achieving efficiencies greater than 90%. Obviously, the current output is limited by the size of the capacitors and the current carrying capacity of the switches. Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum.
When the frequency and modulation degree of the inverter change greatly, the inverter can still respond quickly and work normally. This article proposes a modular switched-capacitor inverter which employs a single dc source. The inverter can gen-erate seven-level and obtain triple voltage gain.
