When selecting the DC link capacitor, it is important to consider the ripple current and capacitance. The ripple current depends on the source inductance, frequency, and duty cycle. You can calculate the ripple current by using the inductor voltage formula and considering differe...
To calculate the voltage across an inductor, the formula is: All you have to know to calculate the voltage across the inductor isL, the Inductance of the Inductor which is expressed in units, Henry, and the derivative of the current going through the inductor. Example If the current going t...
Saturation Currentis the maximum amount of steadyelectrical current an inductor can handle before losing effectiveness. An inductor’s core can only hold a certain amount of magnetic force. When it exceeds this limit, the inductor will cease working correctly. Whereas the Rated Current is the maxim...

A DC motor consumes 36 MJ of energy when connected to 230 V FOR 2.5 hours. a. Calculate how many kWh is the amount of energy mentioned above. b. The power taken by the motor from the mains. c. The current taken by the motor from the mains. An inductor has an inductance of 17 H...
Bode plot 2.2 How to Calculate Inductor To calculate the value of the inductor, LIR is used. LIR is a coefficient that represents the amount of inductor ripple current relative to the maximum output current. In every cycle, inductor current is LIR times of max output current from Equation 3...
An inductor is basically just a coil of wire. The inductance of an inductor is a measure of its ability to store energy in the form of a magnetic field; when the current in the coil changes, it follows from Lenz's Law that the magnetic field will induce motion of charges in such a...
The inductor current decreases to zero for a period in the DCM, as shown in Figure 1. Ipeak ton toff TS Figure 1. Inductor Current Waveform in DCM In the DCM, the peak current of the inductor need to be calculate with formula (6), Where VIN(MIN) is the minimum input voltage. ( )...
