Modeling and Control of a Six-Switch Single-Phase Inverter - ETD-db
... To fit the existing systems the inverter designed will need a single-phase three-wire output. One important item to note is that many power sources such as fuel cells do not provide a high voltage output. Therefore several stages may be required. The first option would be to design a standard single ...

An Example of Feedback and Control: Speed Control of Motors
... But suppose we want to be able to vary both the motor’s speed and direction. It’s not so easy to do this, especially if we also want to use a motor that requires more current than the LogoChip can directly provide. Fortunately there is a clever solution to this problem known as the H– Bridge. This c ...

... For three-phase loads, a voltage unbalance of one or two percent is usually not a problem. However, larger voltage unbalances can cause many problems. For example, three-phase motors with 5% voltage unbalance exhibit 25% decrease in torque, 50% increase in losses, 40% increase in temperature, and a ...
