Based on the previous H bridge that I have built with the help from Goldsmith, FvM and andre_teprom (refer to: https://www.edaboard.com/threads/255503/), I designed a h bridge circuit with pwm feedback.
The schematic and simulation results is shown as in attachments.
The result shows the...
Thank you my friend, by your enlightment I just found out the reason of the phase problem.
I put the wrong side of the voltage marker on the circuit. Because current flows from left to right within the vcccs but right to left at output therefore the + end of Vc is on right side and - end is on...
No, i was referring to the voltage across the output ends of voltage controled current source G1 in my shcmatic...now the problem about how the switches can be controled has been solved, i feel confused with the characteristics of that vccs...
Thanks! You are right, that 10V node wont give any supply voltage, but actually I found that I don't need a supply voltage because ideal switches will be controled by +/- 0.4 v.
What I want is the voltage generated from the output of that vccs, and I expect to have it in phase with V1. But my...
Hi FvM:
Supply voltage is 10V as shown on the schematic.
It should be alright to perform a simulation.
Thanks

So I think that is one reason why my supervisor asked me to use ideal switches first because there are some non ideal characteristics by using fets.
One thing I...
There is no designated operation frequency and o/p voltage, duty cycle 0.5. According to my supervisor, this test is simply to make V1 in phase with the output Vc1 while according to his idea of the operation of vccs and h bridge they should be.
Do you think there will be something wrong with...

Thank you for your comments goldsmith.
I wish that I can use mosfets. The reason that I use ideal switches is because my supervisor forced me to do so... quite strange eh?
I tried different types of sources, include sin wave and V pulse, configured to square wave...
Hello! I'm a newbie on this forum.
I'm currently desinging a h bridge circuit based on a larger scale energy harvester project. Unfortunately, I'm now stucking on the schematic design by using pspice simulation.
The circuit is actually a quite simple h bridge by using ideal switches as the...
