WebApr 12, 2024 · As it is, the V1 on time is too long; watch inductor current in the first cycle. The converter is also operating in discontinuous mode despite a significant load, so the output voltage swing is huge. I'd say start design calculations as if this were a 36v buck converter, and then work in how much of the on-time can be shared by the 12v source. WebMar 18, 2024 · 5. Mar 18, 2024. #1. Dear all, I am trying to simulate my synchronous buck converter and I managed to implement complementary signals to driver two different transistor. The issue is as follows: 1- I inserted dead-time (green circle) but the problem is that at the start of the period two signals overlap together which will cause a short circuit.

WebMay 4, 2024 · Here's what a quasi-real setup would be: Note the PMOS (usually when in high side), driven by a signal that's between GND and 13V (or close, some losses simulated) -- as the other answers have suggested --, and some parasitics. Instead of V2 there's usually some sort of control, voltage- or current-mode, that's a different question, but one … WebApr 28, 2016 · Click for full-size: To get this simulating near real-world values, I did the following: Set "Start External DC Supply Voltage at 0v" in transient options. Replaced M1 with a real model (right-click, "Pick New MOSFET".) Same with D1. Increased simulation to 50mS to see the settling value.
