The key principle that drives the boost converter is the tendency of aninductorto resist changes in current by creating and destroying a magnetic field. In a boost converter, the output voltage is always higher than the input voltage. A schematic of a boost power stage is shown in Figure 1....
This simulation shows a simple boost converter. The coil is the heart of the action. As you can see the coil is 4 uH, a suitable value to operate at 200 kHz. It must carry an average of 30 A at 45 V, if you want 100 V at 8 A. I added a 0.2 ohm resistor to represent paras...

The first, continuous-conduction mode (CCM), is where energy in the inductor flows continuously during the operation of the converter. The increase of stored energy in the inductor during the ON time of the switch is equal to the energy discharged into the output during the OFF time of the...
3.13 Efficiency Estimation The total loss of the boost converter (PTOTAL) can be expressed as the sum of the losses in the device (PIC), MOSFET power losses (PQ), diode power losses (PD), inductor power losses (PL), and the loss in the sense resistor (PRS). PTOTAL = PIC + PQ + ...
Conversely, if VCOMP falls below this threshold, the converter current flows in the reverse direction. V(COMP) V(COMP,CL +) V(COMP,CL 0) V(COMP,CL-) Negative Curren t Limit 0mV Positive Curren t Limit V(CSA )-V(CSB ) Figure 2-2. Control Function for the Peak Current Sense ...
