PWM Switch LTspice: Mark Dimattina offers a way to implement the PWM CM version in LTspice. Thank you for sharing your models Mark.
In LTspice, we can measure the ON time as 3.5us and a period of 6.14us, giving a measured duty cycle of 57%. With a boost converter, the current in the inductor must be continuous for this equation to hold true. A boost converter is used as the voltage increase mechanism in the circuit known as the 'Joule thief', which is a circuit topology used with low power battery applications, and is purposed at the ability of a boost converter to 'steal' the remaining energy in a battery. The energy remaining would To be clear, the other common use of the boost converter is for AC to DC power supplies for power factor correction and that requires a complete and separate treatment. When I say DC to DC, I mean converters with an input voltage that is positive and does not move up and down quickly. LTspice lets you program in capacitive loss versus electrical engineering department california polytechnic state university: san luis obispo buck-boost dc-dc converter with input protection system for the energy harvesting from exercise machines project by byung-jae david yoo sheldon chu 2013 – 2014 Hi All I have setup a simulation in LTSpice with components selected that I wish to create a real PCB for but wanted to simulate it first. I am having a it of an issue with the design I used LTpowerCAD initially to workout what components to use, It takes in 12V and outputs 40V @ 7.5A.

now from the boost converter mathematics, i understood the following (i will take the o/p voltage as 5v for ease of calculation , and that i m not thinking about the buch part now ): (1) to keep the inductor peak current higher than 2x of normal current, i need to keep the inductor small.
