Can a DC power supply have a positive and negative voltage output?

Now, you have both a positive voltage output and a negative voltage output. Sometimes you may need both a positive and negative voltage output from a DC supply for applications or testing. To do this, you need to at least two DC power supplies or one with multiple outputs which has a floating o

How do I get positive and negative voltage outputs?

When you have two single channel DC power supplies or a triple output power supply, here are some suggestions for you to get the positive and negative voltage outputs you need. Connect the two channels/supplies in a series configuration.

Can a current sensing design be used for a negative output power supply?

There are many current sensing designs available in the market but most of the sensing designs are designed for sensing current in a positive output power supply application and cannot directly be used for negative output power supply designs.

Can ti design a Hall current sensor with a negative power supply?

Designer can directly series the hall current sensor with negative power supply since hall current sensor in general is a galvanically isolated and capable of monitor DC or AC current. TI design and produce more than ten high performance hall current sensors to meet most industry applications.

How a current sensing amplifier can be used for negative power supply?

Current Sensing for Negative Power Supply Based Isolated ADC For sensing current of a negative power supply, the designer potential firstly considers a current sensing amplifier since these parts was widely used for current sensing with designed for performance, compact package, low cost and sourcing easy.

How to convert negative output voltage to positive feedback voltage?

To convert the negative output voltage to a positive feedback voltage, a level shift circuit is implemented. It uses a current mirror circuit built with two inexpensive PNP transistors, and one NPN transistor to regulate the output voltage.
