So basically when the current goes to zero on the secondary side, there is a oscillation between the main inductance and the various capacitances (such as Coss of Mosfet and Tranformer). 𝑉ds(𝑡) = 𝑉𝑖𝑛 + 𝑛 ∙ 𝑉0𝑐𝑜𝑠𝜔0(𝑡 − 𝑡0) So you have a n of (1/7) . Vin = 24V Vout = 180 So around Vo is 180 V . The Equations leads to a minimum of : Vds = ...

If your schematic is correct then you are using the DA2032 part. From the datasheet it appears to be a 3A part. Taking a look at the datasheet of the LT3757: they recommend taking 20% of the specified current sense (100 mV minimum). On top of that the RC filter at the sense input lowers this sense voltage more. Based on this: you should work with 20% of CS ...

Shortly, it's the effect of \$V_L=L\ di/dt\$. Here's the equivalent diagram of your setup (neglecting the real model of the inductor): simulate this circuit – Schematic created using CircuitLab The inductor sees a positive DC voltage for the half of the period and a negative DC voltage for the rest of the period. So, from \$i=\frac{1}{L}\int{V_L\ ...

Main limitation factor is temperature. Each coil is heated by its own current and they all heat the transformer as whole. Also, some heat dissipates in the core itself. So, you can trade the current of one output coil to another. But usually each coil is made by the wire of specific cross section, fitted to nominal current of that coil. Total power rating of ...

Assuming that you are referring to a Cockroft-Walton voltage multiplier, please note that as more stages are added the available energy output significantly descreases. You would be real lucky if the CM multiplier didn't reduce the output voltage to less than the secondary voltage of the NST! From my own experiences over the years, the ten stages that you ...

The output pole of this compensation network (type 2) is set by the output capacitor of the optocopler + the pullup resistor of the primary's side controller. First he calculates the output capacitor in order to set a pole @ fp, and for this case it would require a capacitor C_calc = 581pF connected to the output of the optocopler. However, the optocopler ...

In a flyback transformer, a gap is mandatory for energy-storing reasons but also for stabilizing the inductance in production. We can show that the magnetizing inductance of an iron-core inductor featuring an air gap is expressed by: \$L_{mag}=\frac{N^2A_eµ_e}{l_m}\$ with \$µ_e=\frac{µ_rµ_0}{1+µ_r\frac{l_g}{l_m}}\$ in which \$µ_e\$ represents the ...

I know I am bit late on this, but I think my answer may help.somebody. Why not give the task of smps to the chip which is designed for it? Use SG3525 in push pull configuration. Short it's pins 1 and 9. Then supply voltage from 0 to approx 3.6 to its pin 2 to control the duty. You can use the PWM output of uC and have low pass filter ahead to convert the ...
