The variable resistor in Figure 2 uses only two pins. Figure 2. Old Circuit Symbol Figure 3 shows the circuit symbol when the variable resistor is used as a potentiometer. It is obviously different from that shown in Figure 2. Its three pins are independent. This is how to use the ...
5. A charge/discharge current detection circuit according to claim 4, wherein the variable resistor comprises a first circuit having m serial circuits connected in parallel, each having a resistance and a switch connected in serial, a second circuit having n serial circuits connected in parallel,...
To have an variable output, R4 can be flipped clockwise, with S3 in the closed position, and getting rid of R5 from the circuit. The output voltage can now be operated by the R4 resistor solely. When the position of SPDT switch S2 is in 1, the highest output current can be accomplishe...
Problem to be solved: to provide a variable resistor capable of continuously varying resistance values by a simple configuration. An output voltage control circuit 10 for performing feedback control of an output voltage in a circuit for converting an input voltage VI and outputting an output ...
Fig. 6. (a) IVs of a solar module calculated for different irradiances (red curves), IVs of a load resistor calculated for three RL values 50, 100, and 400 Ω (blue lines), battery IV calculated for VOCB = 3.6 V (dotted black line), common battery-load IVs are presented with blac...
Once the highest output voltage portion of the design has been entered and verified, change the lower resistor in the feedback path (R2 in Figure 1) for the lowest output voltage. Name and save the design in EE-Sim and change R5 to a value that will give an output for the lowest...
An integrated variable resistor in MOS technology includes two parallel-connected transistors (T1, T2) whose electrodes are floating relative to the substrate (8). Its resistance is controlled by mean
Selective sWitching of the branches can be realiZed by a set or reset S1 control bit. SWitches 320 are alWays turned on When the gain circuit is in use. [0006] As evidenced from the above discussion, it Would be desirable to have a resistor ef?cient gain circuit Which reduces resistor ...
a first resistor having a trimmable variable resistance and connected between the first power supply and the first selector input terminal of the n selector circuits; and a second resistor having a trimmable varying resistance and connected between the second power supply and the first selector inp...
Variable frequency drives (VFDs) with diode rectifier front end are typically equipped with a resistor-contactor arrangement to limit the inrush current into the DC bus capacitors, thereby providing a means for soft charging the DC bus capacitors. Because of the mechanical nature of the magnetic ...
