Hello,
i want to generate .hyp file for SI and PI simulation in hyperlynx. during conversion every thing seems OK but converted stack up in hyperlynx have dimensions not similar to what i have set up in allegro. i am using allegro 16.6 and hyperlynx 8.0 each installed on different...
Hello, i am facing problem without fan out feature of auto router in allegro pcb editor. the through hole component should be connected to plane without via but auto router is using separate via for its connection to plane. images of before auto routing and after auto routing are attached...
has anyone used design reuse module in allegro through orcad capture? please let me know the stepwise process of using .mdd file in version 16.0 of orcad.

i am having problem in design reuse with allegro. i am using hierarchical design in which two external designs are instantiated twice.(total modules = 4(M1,M2,M3,M4)) but after all steps given in capture tutorial and final netlist generation when allegro window opens, it has all the four modules...
hi, i am in doubt about using the triac with micro-controller directly without any isolation. many application notes particularly from microchip indicates that triac can directly be driven by uc. but what i think is that any uc cannot aceept input at its pins that is much greater than its vdd...
Dear Goldsmith,
i have gone through the thread and i found it very useful but is there any procedure to find out the power and frequency of a randomly selected core through some experiments. also consider this **broken link removed**. what kind of transformer it is? what is its core material...
yes please tell me how to select the best core for a particular application. also tell me what is wrong with these cores.
i have measured them & their value is unchanged.
I=V/R*[1-exp(-r*t/L)]
I=12/0.5*[1-exp(-0.5*190u/300u)]
where 0.5 is Rds(on) of IRF740
i am using the cores whose snaps are attached in my previous post (yellow/white & green/blue). i have selected it randomly. i started winding the core with 18 AWG wire until my LCR meter gives 300uH.
Capacitor used is 47uF 400V polar.
My problem is that i theoretically should get the peak...
thanks for your response. please consider my thread "DC-DC boost converter problem". & let me know for further info .
waiting for response.
thanks in advance
i am using yellow/white core to design an inductor with L=300uh, i have wound 57 turns of 18 gauge wire and checked it with indutance meter to get the desired inductance. with 12V and for 190us, i should get a peak current of approx 7.7A, but when i constructed and used the inductance, it gives...
Please find the attached pictures of cores i am using to design inductor. Please advice about its specs, material. whether it can give incorrect reading with my LCR meter its inductance increases as current through it increases? and whether it is suitable for application with V=12V,Imax=8A...
Please find the attached pictures of cores i am using to design inductor for boost converter. Please advice about its specs, material. whether it can give incorrect reading with my LCR meter its inductance increases as current through it increases? and whether it is suitable for boost converter...
what kind of measurements can be used to identify the real problem of adding resistance in circuit? i am more intrested in finding the faults/limitations that are making my circuit to depart from ideal behavior before going to adopt some other design.
i have plans to design a 220v 50hz inverter...
