12V to 24V DC DC Converter SG3524
The frequency is set between 80 and 100 kHz (low critical value). A lower frequency requires a higher inductance, which increases the volume and losses. A frequency too high led to losses of significant switching in the transistor and additional losses in the inductor due to skin effect.
# The resistance of the inductor L (neglecting losses iron)
# The resistance from the state of the transistor Q RDSon (on spare switching losses)
# The voltage drop in the diode
# The series resistance of capacitor C (ESR)
The value of the inductor affects ripple through the current, hence the current peak through the other elements.The study shows that a theoretical value of 40 to 50 µH is a good compromise.
With a battery of 12V, output 24V – 10A and a yield of 90% is the current drawn by 22.2 A. If the battery drops to 10V, current rises to 26.6 A
