Can LCL Filter Convert AC to DC for Half Bridge Section?

[PhysicsTest]

The idea is from the AC what is the maximum DC voltage can be generated with different rectifying techniques,

In the above circuit if the input AC is sine wave of $A_{RMS}$ then if half wave rectification is done the maximum DC voltage is as calculated above is $\frac{2\sqrt2 A_{RMS}} {\pi}$ and if full rectification is done the maximum DC voltage is 2 times the above $\frac{2*2\sqrt2 A_{RMS}} {\pi}$ = 1.8*Arms. Similarly there are some rectification techniques, i want to calculate the DC voltage for them as next step.

Short Answer: The peak value of the rectifier AC input voltage.
Real-World Considerations (corrections):

• subtract the forward-voltage of the rectifier(s)
• subtract the voltage drop of the supply voltage (typically from a small transformer)

Those items vary with the load current.

If you want the usable voltage, account for the the ripple due to the filter capacitors discharging between the peaks of the rectified voltage.

The above is valid for Half-wave, Full-wave, and Full-wave Bridge rectifier circuits.

In the rare instances of using a Voltage Multiplier rectifier circuit, the above holds for each stage of the multiplier. (don't go there if you can avoid it! the calculations are a real pain))

Cheers,

I recommend looking at the appendix of this old National Semiconductor Audio Handbook. It has a nice treatment of rectifiers, especially the voltage vs. load vs. filter performance.

The reason for using a switching rectifier is usually because there is a high load and the power factor must be corrected. The circuit will then need to be operated to sink or source current, proportional to voltage, from all three lines. While doing that, the circuit needs to maintain the voltage in the reservoir capacitor.

I actually have that handbook:

Can you post a pic or a scan of the Table of Contents for that one Don? I know most of National's handbooks/databooks, but have not seen that one. Thanks

It was a little hard to get a good photo of all the Table of Contents pages but this will give you an idea maybe:

Beauty. Do you know if NS has posted a PDF of this online?

I don't know. I haven't looked. Here's another photo to give you an idea of the contents:

Due to it's age, the yellowing makes it really hard to photograph.

edit: maybe you can download this image and enhance with your tools.
