- Operate circuits at voltages as high as 540V acJohn S Lo Giudice Vipin BothraEnergy meters, heating/ventilation/air-conditioning (HVAC) systems, and high-power equipments that run on three-phase ac inputs pose a challenge to power-supply designers because nominal input voltage can be as high as 540 V ac. The challenge increases if the power supply...05-06-2023
- Simple dual constant-current load tests low-current power suppliesToday’s small electronic appliances, such as washers, dryers, and stoves, use switched-mode power supplies to replace bulky, heavy, linear-power supplies. The engineer testing these power supplies, which range in current from 50 mA to 1 A, typically uses...18-08-2022
- Minimize Noise in Power-Supply MeasurementsEliminating excess noise from an oscilloscope probe yields better measurements You must minimize noise when measuring ripple in power rails because the ripple’s amplitude can be low. Oscilloscope probes are essential measurement tools, but they can introduce noise and...12-03-2012
