Power converters with a full-bridge topology are frequently used in telecommunications and servers that need to be compact, efficient and cost sensitive, making them more complex. Switching patterns for all the main primary switches including synchronous rectifier switches need to be validated after the first protype is built. This complex validation requires proper measurement of switching patterns to prevent catastrophic switching patterns. Expertise and the right measurement tools are essential when identifying unexpected events in the converter switching process.

Stable operation in all circumstances is essential for power converters. Different working conditions, such as load steps, startup/shutdown sequences and input voltage variation, apply to most converter types. In addition to the standard feedback control loop, integrated pulse width modulation (PWM) controllers provide extended functions, such as line feed-forward loop control and soft-start control.

Sometimes auxiliary functions generate emissions infrequently, making it challenging to locate and isolate the root cause. An instrument with a very fast FFT analysis capability is essential to find infrequent events efficiently.

An offline AC/DC switching converter has no separate bias power supply that provides power to the control integrated circuit itself. Here, an auxiliary primary winding and discrete components are added to supply power to the control circuit. Verifying this circuitry is essential and requires accurate and detailed signal level and timing measurements. The startup sequence takes a long time, which needs to be taken into consideration in the measurement and requires an instrument with sufficient memory.
