The drive transformer windings must be isolated for the full converter operation voltage, same as the output transformer. nevertheless the drive transformer provides only functional isolation. The output transformer typically needs reinforced isolation, hence higher creepage, clearance and test voltages. If voltage stress refers to the isolation
I see a misunderstanding involved with the 280W Half Bridge Converter design example. MC34025 is no current mode controller. It's a voltage mode controller with additional current limit and shutdown function. The difference is obvious by the fact, that the current sense input is compared against a fixed threshold rather than the error amplifier out
A typical BPF should has 1dB ( more or less ) Insertion Loss at those frequencies, not 10dB. This Insertion Loss will surely reduce the Sensitivity of the Receiver but it's obligatory.. If the Antenna Impedance varies so, I believe this antenna is not very well designed.nevertheless, Signal Levels are pretty high at FM Band.So, I don't think that t
Very little substantial information yet, although it can be easily get by performing differential diagnosis. E.g. disconnecting the motor power and operating the limit switches manually. My first guess is contact arcing of the motor relays, causing electrical interferences. If it's a bidirectional drive, do you protect the relays circuit against
LVDS standards are based on 100 ohms differential impedance and if LVDS receivers are equipped with internal termination (some FPGAs, receiver ICs), it can be expected to show 100 ohms. It can make nevertheless sense to use a lower differential impedance, e.g. if the pairs are routed on inner layers with low substrate height, termination resisto
RS605M is not an appropriate choice for this kind of application.It's used in HV applications rather than Low Voltage/High Current. 2200uF/per Amper is a good rule of thumb for 50Hz applications.But 45 degree is -thought- coming from rectifier diode ( by radiation ) if they are close.But nevertheless 45 degree is not a serious issue for electrolyti
The performance difference is nevertheless remarkable, at least with Quartus tool. The capability of a synthesis tool to find optimal solutions can't be predicted, you need to try. I can write a parameterizable solution in VHDL with the same performance as the post #10 code, but I didn't succeed in Verilog. library ieee; use i
Hi, I am trying to measure the energy consumption of a PC system in a high resolution and sample rate (to measure the effect of different algorithms on the power consumption). The expected current should be under 2.3A (550W/230V='power rating of power supply'/'wall power'). I ended up buying a ARM Energy Probe Measuring Card ( https://www.far
Holtek is providing a Touch MCU Workshop for download, but it has apparently only precompiled libraries, no source code. I would use the workshop as a starting point nevertheless.
Output Power should be vicinity of P1dB. In fact, there isn't any convention about that because some manufacturers use P3dB some of them P1dB. nevertheless, P1dB Compression Point is chosen and Input Power is adjusted in according with that.Because Optimum Load will be used to achieve max.
Note the MAX5875 Eval board used three PCB ground sections: AGND, DGND, CLKGND. Yes it has. This kind of design works fine for evaluation circuits with one and only one mixed signal device. It's not feasible for most real world designs. Other design details of this board can be nevertheless implemented.
Easy peasy has answered your question from a designers/instrument manufacturers perspective. To investigate the detail effects, perform a simulation. My assumption is this: If your voltage control loop is compensated reasonably, stability margin will rather increase than decrease with capacitor degradation. You'll nevertheless observe unwanted e
It would be better to have a consistent schematic with actual component values. The 33 mohm + 30 ohm point seems to contradict other specifications, you can't drive more than a few 100 mA into this load with +/- 12 V supply. Also base current sourced by 2.2k is far too low. nevertheless the circuit has no ability to damage a correctly connected
A diode-capacitor circuit might buffer the inrush voltage drop. nevertheless I encourage a test with separate power supplies to sort out things.
Drawing error. R5 has to be connected to ground not output. As sketched, the circuit misses negative feedback. The corrected circuit has CMRR but high sensitivity to resistor mismatching. Also asymmetrical input impedance. Source impedance mismatching affects CMRR. nevertheless it's often used as cheap differential input stage for audo.
LVDS doesn't have large common mode range, RS422 is probably better, common mode chokes and common mode termination may be useful nevertheless. Or use transformer coupling.
The 64 logic levels are normally high, and I want to detect if any of them go low in a certain period of time. You're probably familiar with this grid arrangement, similar to the way a keyboard is scanned. The demo below has 9 sources. Each source has two diodes which steer the signal to a 3x3 grid. As soon as you det
Hi ThisIsNotSam, Thanks for your insight! I am more and more suspect you are right. I am using a 9 metal layers version in my layout while the filer file can cover till 11 layers. nevertheless, I did not find any place to change the metal layer definition... When you said to "edit" the file, did you mean massive manually delete the lines th
FPGA logic implementation uses configurable logic elements as low level primitives not transistors. In so far "switch level" is useless for FPGA implementation. Switch level description could be translated to FPGA logic nevertheless. Switch level can be at least emulated in VHDL using std_ulogic states.
Do you want to use the pressure transducer with its dedicated amplifier, or include the amplifier function in your design? In the latter case, does your design need to provide fully galvanic isolation like the shown bp amp? The stimulation waveform generation and respective control algorithms are apparently beyond the scope of this thread. Never
