With the stardard solution based on a triac and ZVC circuit I have verified same problems: Triac damage and electronic control circuit damage after triac damage, very short duration time for the halogen lamp, imperfect light intensity control for the final application of the system. This lamp is...
Hi,
I have to drive a resistive load. It is necessary to control the output power. The best way is to drive the output voltage of a DC/DC converter based on an IGBT. The Triac can be used with ZVC, but It is not ideal for the load.
I think a solution based on an AC/DC (based on a 4 diode)...
I'm using an halogen lamp power controller based on a Zero Voltage Crossing Circuit, Triac and microcontroller. The experimental result of this solution is not soddisfacent.
I would change this lamp controller solution with a DC/DC variable voltage controller that is able to adjust the output...
The problem is related at the UAC becouse if I set UAC = OFF, Cadence works very well.
But the batch file attecched don't resolve the problem if I maintain the UAC = ON.
I have installed and used Cadence Orcad Allegro SPB 16.5 for two days.
Then, the System administration have removed my user account from the aministrators Group on Windows 7 x64 bits and to resolve a problema with same program that did not start proprerly he have changed the uac limitation of my...
I am interesting to learn the CANopen protocol.
I would drive an electrical motor by CANopen interface.
For this reason I am finding a CANopen stack, api, driver or firmware library free or open source.
Can anyone suggest me a solution?
Can I assign the IMPEDANCE_RULE (or other SI Propriety) to a user defined propriety?
I'd like to create an additional artwork film with Controlled Impedance information.
Hi,
I am any problem to porting the FreeRTOS Demo Project for STM32l15x microcontroller to the STM32L-Discovery Board.
I would know how I can make a template project with free main that I can use with FreeRTOS and the STM32L-Discovery Board.
The Ide that I use is IAR EWARM.
When I do the porting...
Hi,
I have two boards (one in FR4 and one in roger) connected to each other by two Samtec connectors.
I have all models necessary for the SI simulation (transmitters, receivers, ferrite bead and connectors samtec).
I have done correctly (I assume) the setup of the models.
Allegro PCB SI is able...
Hi,
I have this problem: I have a spice model of a connector. Allegro PCB SI can extract the Topology with this components but it is not able to do the simulation.
Re: PCB Editor: DRC error & via-Shape conn. do not produced. bug or Migration Problem
Dear praveenlb.
I think that the description of the problem is not clear.
I know very well how PCB Editor works, the difference between the Static and Dynamic Shape, how the static and dynamic shape work, how...
Re: PCB Editor: DRC error & via-Shape conn. do not produced. bug or Migration Problem
Dear praveenlb, The constraints manager is set correctly: The clearance via to shape is configured at 200um. The shapes are: 1) the shape in the inner2 (GND Plane) is "dynamic"; 2) the shape in the inner3...
PCB Editor: DRC error & via-Shape conn. do not produced. bug or Migration Problem?
Hi everyone,
I am using Cadence PCB Editor 16.3 to develop a board (4 layers).
I have 3 vias connected to the GND_RF net.
The Top Layer and Inner2 Layer have a plane connected to GND_RF.
The Inner 3 Layer has a...
