12v booster to inverter

Which IC can be used for high power DC 12V to 30V boost converter?

The popular IC SG3525 PWM IC could be used as high power DC 12 V to 30 V boost converter circuit application as shown above. All the relevant circulations for determining the L1 coil details, the RF feedback resistor value and the output capacitor values are all furnished in the diagram itself.

Can a DC-DC converter convert 12V to 400V?

DC-DC converter, 12V to 400V? Is this possible? To be able to charge a high voltage battery (~400V) from solar panels I need a dc-dc converter that can boost up the voltage from the low voltage system (~12V) to the higher voltage. The power needed is about 400W, or 1A at the output.

How does a boost converter work?

In a boost converter, the output voltage is always higher than the input voltage. When the switch is closed, current flows through the inductor in the clockwise direction, and the inductor stores some energy by generating a magnetic field. The polarity of the left side of the inductor is positive.

What is a 12V to 30V power converter?

DC -DC converters intended for stepping up car battery voltage are often configured around a switched mode type of power supply (SMPSU) or a power multivibrator, driving a transformer. The 12V to 30 V power converter I have explained in this article employs the device TL 497A integrated circuit from Texas Instruments.

Should I use a single inductor boost converter?

It's surely no good idea to use a single inductor boost converter for this. Just consider that switching losses are roughly proportional to the switched power, which would be 70A*400V = 28kW. Also you need a switch transistor with 400 V capacity instead of 24 V for a transformer push-pull converter.

How do you calculate a boost converter?

for a boost converter, the inductor size must be >= Vin*D*Ts/ ( il'), where il' = allowable inductor peak to peak ripple current. this small signal current ripple will ride on the average current you are going to draw at the output. so, the peak output current = avg (output current) + il'/2.
