Bench power supplies can be basic, and they can be complex. This tutorial video covers essential, basic bench power supply tips that all electrical engineers should know. They are crucial for electronics work, lab work, electrical design work, and can blow up your devices if they arent used properly.
This video explores 9 tips and capabilities you should look for in your bench power supply.
Load regulation — the variability in the output V/I due to change in load. Some loads will not tolerate voltage variations greater than a few percent
Line regulation — the variability in the output V/I due to change in AC input
Programming accuracy — the quality of the programmed value being near to the actual V/I
Read back accuracy — the quality of the displayed value being near to the actual V/I
Resolution — the smallest value of V/I that can be programmed
Output noise — consists of common mode and normal mode
Transient response — time taken for the output voltage to return to the programmed state after a disruptive change in load current
Sense connections — local and/or remote sense capability
Interface — front panel and/or remote (LAN, GPIB, USB, RS232, etc.)
Low noise, excellent regulation, and remote sensing capability that reduces the voltage drop across load leads, are the desired characteristics in a power supply.
When dealing with power, safety comes first. Sometimes when devices fail, it may be catastrophic. It is important that a power supply not only protect itself, but also protect the DUT. Protection circuits in the power supply can limit the voltage or current to a preset level or shut down the power supply when an overvoltage or overcurrent condition occurs. Some power supplies also have a down programmer circuit to quickly discharge the DUT while some, upon receiving a fault trigger, are able to open a relay and isolate the DUT from the source of the power.
