PROBLEM TO BE SOLVED: To provide a semiconductor testing device having a positive/negative DC power supply unit and capable of shifting both output voltages of positive and negative power supplies, by eliminating the need for a DC-DC converter for an exclusive voltage shift, in an individual I...
The 2 main sources of DC power are from DC power supplies and batteries. Therefore, we will show how to connect these devices so that they produce negative negative. DC Power Supply Let's begin with the DC power supply. So a DC power supply normally has 3 terminals: +, GND...
