In this video, we introduce the concept of the dc-ac converter. In particular, we look at the full-bridge converter and show that it can be used to produce an ac voltage from a dc voltage source by controlling the switches in a specific manner. If you haven't seen the bridge converter before, we discussed its use as a dc-dc converter in: • The Full-Bridge DC-DC Converter Outline: 0:00 - Principles of Operation 8:04 - Tri-state Mode of Operation 12:44 - Calculation of RMS Voltage
