### How does one compute the ripple currents seen by a rectifier filter capacitor?

Suppose one is designing a full-wave rectifier bridge, with a known maximum current load, and a known input inductance. Assume three-phase for this example, though the same concept applies to ...

### How to determine position from gyroscope and accelerometer input?

I have a 3-axis accelerometer and a 2-axis gyroscope. I intend to measure something that only moves in the X and Z axis. I've heard of using Kalman filters to smooth out the acceleration vectors, but ...

### Advanced Math in day to day Electronics? [closed]

So i've been watching the MIT 6.002x Classes and they are really interesting, I feel like i've got a good grasp of Circuits and the Basics (I graduated with a CS degree...but EE appeals to me too). ...

### How does one compute the ripple currents seen by a boost converter output capacitor?

Suppose one is designing a boost converter, with a known maximum current load, and a known inductance: The ripple current seen by the output capacitor is critical. If that current is too high, the ...

### transfer function of a full bridge diode rectifier

I'd like to find the s-domain transfer function of a full bridge diode rectifier with capacitive output filter. Surprisingly, there doesn't seem to be much literature on this. Analytically, I am ...

### Why does the base-emitter voltage of a BJT decrease with temperature?

According to Sedra/Smith Microelectronic Circuits, $v_{BE}$ changes by $-2\text{mV}/\text{°C}$. I cannot understand how this could possibly be the case given the equations I am familiar with. ...
