Cascading two boost converters [duplicate]
I have assembled a cascade converter circuit. My main goal is to accumulate a voltage of 80 volts on a C6 1000 µF capacitor in about 6-8 seconds. The problem is that I am using a 3.7 V battery. If I ...

Constant output voltage in buck-boost converters
I'm a self-taught student. I'm trying to understand the working principle of buck-boost converters in continuous conduction mode.
When the switch is turned on, the equation describing the inductor is ...

Find inductor for XL6019 circuit boost converter
I need a way on my PCB to step up 5V to 12V (with currents up to 2A). I've been looking at the XL6019 IC and tried to copy the design from the sample circuit of the datasheet:
I'm currently stuck at ...

Purpose of capacitors near the input of DC/DC boost converter
I recently bought this DC to DC boost converter (input from top; output from bottom). It has all the parts as a usual boost converter topology suggests: a mosfet, a diode, an inductor, and capacitors ...

Reversible 4-switch buck-boost?
Can a 4-switch buck-boost be reversible?
The base scheme seems symmetrical but I did not find any reversible design.
Do you have an exemple of such a design?

How does a boost converter allow for a gain in output voltage by just switching the positions of the inductor and switch?
I get that in a buck converter, a low pass LC circuit was attached and this effectively filters out high frequencies. If the bandwidth is configured so that it is lower than the switching frequency, a ...

DC-DC Boost Converter \w Inrush Current Protection - Voltage
I wanted to dive in Power Electronics and create a 24V DC-DC Boost Converter that would run from 2.5 to 5 V power supply. 80% efficiency was assumed, and 30 kHz frequency chosen for the PWM.
Initial ...
