Determine how many seats of the license are allocated to each group (for a multi-seat license). However, in a real converter where the switching node has some parasitic inductance, the switching time can excite some transient that creates excessive high-frequency ripple on the switching node output voltage/current. View and edit the users account member information. Note that this is normally defined in terms of the voltage drop across the high-side MOSFET and the rectifying element (V(diode) in this case, could also be the low-side MOSFET): If the converter is in the discontinuous mode, the output voltage will be a function of the inductance. A user can be added as a member to any number of defined groups for an Altium Account. Working with the Simulation UI in Altium Designer The schematic below shows the circuit above from Case #3, but with larger capacitance on the output. Altium 365 Viewer is a simple and convenient way to view and share electronic designs through your browser. So I simplified it over and over again until I got to a very basic resistor and capacitor circuit. Wouldn't it be convenient to have sources, probes, results, and more in a single place? This would then allow one to implement a much more precise and simple control algorithm, such as you would find built into PMICs for gate drive control; the algorithm just adjusts the PWM signal based on the output to get highly precise power tracking and regulation. The PWM signal is sourced from VP to provide the switching action in the MOSFET. Keysight Licenses Simulation Software Technology to Altium for PCB The goal in a buck converter simulation is to examine how the duty cycle of the PWM signal, the load, and any other components affect the power output from your buck converter, and to verify that the output power demands can be met with the desired loadand operating parameters (input voltage and duty cycle).
