This is a simple means of calculating the required size of the input filter capacitor in a basic power supply, or calculating the peak-to-peak ripple voltage in an existing supply. It works by ...

To see a video on this topic by the author, click here. Figure 1 provides a plot of this expression; it is a circle with a maximum of 0.5, at 50% duty factor and two zero crossings at zero and 100% ...

Our Voltimum Experts answer your questions on a daily basis in our Technical Expertise area. This one, concerning power factor correction capacitors and how to calculate their kVAr, is answered by ABB ...

Abstract: This paper derives a simple analytical expression for the RMS current stress on the DC link capacitor of voltage source inverters which employ the reduced common mode voltage pulse width ...

Abstract: MMC-HVDC has become an ideal solution for the grid connection of offshore wind farms. However, MMC and wind farm have low inertia. Once a fault occurs in the offshore AC system, the fault ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
