High Voltage Dividers High voltage dividers are used to scale down a high voltage for any number of reasons including: feedback for power regulation, or simplified monitoring. Potentiometric ratios as high as 1000:1 or even higher are not uncommon. Voltage divider...

Current Sense Resistors High current sensing is where a low ohmic precision resistor is used in series with the load. To determine the current one measures the voltage drop across the resistor. This is the same principal used by a shunt ammeter. The dilemma facing the...

Riedon’s Balancing Resistors Balancing resistors provide a way for sharing a load between two or more DC-DC converters or power transistors. Using two smaller devices in parallel may have cost, thermal, or physical advantages when compared to one device of...

Inrush limiting resistors Inrush limiting resistors of a few Ohms or less in series with the AC line can address a problem with AC-DC converters where a large surge current may occur as the device powers up and the bulk storage capacitors initially charge. One...
