How Does a Bench Power Supply Negative Supply Invert Work to Control Polarity?

A bench power supply negative supply invert works by reversing the polarity of the output voltage to provide a negative voltage supply. The main components involved are the power supply unit, an inverting circuit, and the output connections.

Firstly, the power supply unit generates a positive voltage. This voltage is then fed into an operational amplifier (op-amp) configured as an inverting amplifier. The op-amp flips the input voltage around zero volts, creating a negative output voltage.

Secondly, the output connections establish how the voltage is delivered to the load. The positive lead connects to the output of the op-amp, while the negative lead connects to the common ground. This configuration allows for a negative voltage output relative to the ground reference.

Next, to control the polarity, the adjustments on the power supply allow operators to set the desired output voltage level, whether positive or negative. The inverting amplifier circuit enables smooth transitions between these voltage levels, ensuring precise control of polarity.

Lastly, the ability to switch between positive and negative outputs facilitates various testing and development applications. This functionality is essential in electronics for testing components, simulating conditions, and troubleshooting circuits.
