Introduction to Power Inverters | What Is 3-Phase Power? -- Part 6

 In 3-phase electrical power systems, the AC system is commonly connected to a DC system. The process of converting DC to AC is known as inversion.

You will learn:

- The operating principle of a single controllable power electronic switch

- How an H-bridge inverter converts a DC voltage to an AC voltage

- The value of null vectors in a switching sequence and what switching sequences should be avoided

- Why pulse-width modulation (PWM) is used to control an inverter

- How a 3-phase inverter converts DC to 3-phase AC
