Q

Power supplies with inductive input filters have the following characteristics:

🔍 Key Concepts

• Behavior of inductive input filters versus capacitive input filters in power supplies • Relationship between transformer utilization factor and the shape/peakedness of rectifier current • How voltage regulation is affected by the way current is drawn from the transformer and rectifier

💭 Think About

• Think about how an inductor behaves with changing current: does it prefer smooth/continuous current or short sharp peaks? • If current is smoother through the rectifier and transformer, what does that do to transformer utilization and peak current values? • Compare in your mind: capacitor-input filter (C first) vs inductive-input filter (L first). Which one is known for very peaky rectifier currents and which one is known for better regulation?

✅ Before You Answer

• Identify which options describe high vs low rectifier peak currents and which describe high vs low transformer utilization factor • Match the filter type that tends to give smoother, more continuous current with the options that imply better transformer loading • Eliminate any option that pairs high peak rectifier currents with good transformer utilization, and consider whether that combination is realistic for an inductive input filter
