For dual-polarity tests, two diodes should be used back to back in parallel. Figure 3. Alternative test circuit that incorporates a small-signal diode Test Hardware Considerations A variety of ...

The capacitor charging and discharging time can be correlated to the duty cycle of the MOSFET gate. Figure 6 shows the voltage behavior across Vcap.

The intrinsic capacitance of the test circuit is 2.8 pF. Using this correction, the values you obtain on the lowest two ranges are accurate to approximately ±2%, or ±1 pF. You must observe capacitor ...

It runs, and confirms his test capacitor is still good. It can’t measure the capacitance, but we’re guessing the resourceful engineer would also have constructed a bridge for that.

The capacitor fit firmly in place and I wasn’t able to dislodge it by shaking the case vigorously. The next challenge was to determine capacitor polarity so I could clearly mark it on the case.

The Marx is dual-polarity charged and contains thirty capacitive stages. Each stage consists of six 32 nF tubular capacitors. The six capacitors per stage are arranged three in parallel to form a half ...

Adding charge pump and LDO components to a boost converter circuit creates a cost-effective power supply for LCDs and other portable applications.
