    High voltage, big capacitor charger: Flyback vs Push-Pull

    Hi, I want to design a high voltage (~450V), big (~10uF) capacitor charger, it must be fast, possibily quite efficient, and around 60W of power. Natural choice would be Flyback, but I would also like to evaluate Push-Pull, or even Full-Bridge, as making it smaller - albeit not indispensible -...

    Two-switch logic-level LS/HS MOSFETs driver

    Thank you for your reply. While the IR2110 looks interesting (and may be useful for some other project), I just realized that I cannot use a two-switch flyback converter for my project, as this topology imposes a limit on the duty cycle that prevents high voltages to be generated (unless one...

    Two-switch logic-level LS/HS MOSFETs driver

    PS: I just realized that the discharging current I will see is only of the primary leakage inductance, not the one happening on the secondary. Returning to the main topic: is there an IC, or a good design made of discrete components, to make a gate driver with one logic level input, and two...

    Two-switch logic-level LS/HS MOSFETs driver

    Hello, Recently, I've been playing with flyback SMPS topology for fun but also to make a reference design for eventual future use in commercial products. Specifically, what I am experimenting with is a capacitor charger (those things for which one usually uses a LT3750 or LT3751) and I want to...
