A full-wave rectifier has one diode burned out in an open condition, what will be the output characteristic of the device?

🔍 Key Concepts

• How a full-wave rectifier normally uses multiple diodes to conduct on both halves of the AC cycle • What happens to current flow if one diode is open in a bridge or center-tapped full-wave rectifier • Compare the output shape of half-wave vs full-wave rectification on an oscilloscope

💭 Think About

• Think about how many diodes conduct during the positive half-cycle and the negative half-cycle in a healthy full-wave rectifier • If one diode is open, during which half-cycle will current still be able to flow through a complete path to the load, if any? • Sketch the expected output waveform across the load when only one path (or no path) is available for one of the half-cycles

✅ Before You Answer

• Verify whether there is still a complete circuit path for at least one half of the AC waveform • Consider if the output can still have pulsating DC or if it must drop to zero at all times • Check whether any remaining conducting diodes can still provide both halves or only one half of the waveform to the load
