What is a triple two-level inverter?
To address the above issue, a triple two-level inverter is proposed in this paper. The proposed inverter adopts a switched-capacitor boost circuit to boost the AC output voltage and to generate a multi-level voltage. Simultaneously, a three-phase full-bridge circuit is assigned to convert the DC voltage into AC voltage.
How does an inverter generate a multi-level voltage?
The proposed inverter adopts a switched-capacitor boost circuit to boost the AC output voltage and to generate a multi-level voltage. Simultaneously, a three-phase full-bridge circuit is assigned to convert the DC voltage into AC voltage. In addition, a novel space vector modulation strategy is introduced to achieve capacitor voltage self-balance.
How to control a switched capacitor inverter/doubler?
The most straightforward is to follow the switched capacitor inverter/doubler with a low dropout (LDO) linear regulator. The LDO provides the regulated output and also reduces the ripple of the switched capacitor converter. This approach, however, adds complexity and reduces the available output voltage by the dropout voltage of the LDO.
Can a triple two-level inverter boost AC voltage?
Currently, many inverters employ inductors to boost the AC voltage. However, this leads to increased current distortion and limits the voltage boosting capability of the inverter. To address the above issue, a triple two-level inverter is proposed in this paper.
How does a voltage doubler work?
In the voltage doubler, the average input current is approximately twice the average output current. The basic inverter and doubler circuits provide no output voltage regulation, however, techniques exist to add regulated capability and have been implemented in the ADP3603/3604/3605/3607. SWITCHED CAPACITOR VOLTAGE CONVERTERS 4.2
