Fixing overshoot in current regulation of AC electronic load

My AC electronic load (previous question here) shall have a constant-current mode. It is being simulated in LTspice. @devnull helped design the circuit for AC loads, but for simplicity's sake in the context of this question, I have reduced the…

PID tuning without a plant model on a slow system

I work at a food processing plant that requires that we hold a liquid product at a certain temperature while it is travelling through piping. A Rockwell PIDE controller controls this process, which is essentially a heat exchanger that opens a valve…

Why does the MOSFET drain potential show this strong turn-off overshoot? How to fix it?

I am trying to build a PV charger (PWM), which I guess is kind of a buck converter. Below is a first LTSpice simulation. V1 are the PV modules, V3 is the battery. V2 is the microcontroller's supply voltage. L1 is my estimate of the wire inductance.…

What are the maximum recommended values ​for SPI/UART/USB series resistors?

Almost always in electronic designs resistors are used in series in the SPI/UART/USB connections to avoid overshoot, and they are encountered in values ​​between 10R and 350R. With what criterion should these values ​​be chosen? The high values…

Quadrature Encoder output overshoot

I have a Faulhaber 1717T006SR DC motor with a build-in quadrature encoder. Here is the relevant bit of the datasheet for the encoder. The encoder outputs are 5V. I want to interface this with an FPGA (spartan 7) which takes 3.3V inputs, so I used a…

Ringing problems on the output of inverter/comparator

I'm trying to drive some RF switches that need 0 to -5 V control logic with a 0 to 3.3 V signal. I found 2 topologies for this level shifting effect, one using a comparator and one using an inverter. Both circuits do the job but have a significant…

Overshoot on dc/dc converter

Any idea on what would the level of overshoot that this LDO can provide? Would that data/information on overshoot would be provided in the datasheet? If not, how should I understand that? I am using this LDO for 5 V to 1.8 V output with a load…

Transformers have inrush current, but is there a voltage overshoot when switched on?

Conventional transformers for 50 or 60 Hz have more or less inrush current when switched on to the grid voltage. Worst-case inrush happens when the primary winding is connected at an instant around the zero crossing of the primary voltage. But is…

Acceptable overshoot, accuracy, and control bandwidth of a buck converter

I am designing a closed loop buck converter and was wondering what would be the acceptable values/performance for control parameters like accuracy, control bandwidth, and overshoot. I know that the output capacitor, for example, directly affects the…

Load capacitance in CMOS circuits

I am studying VLSI and I have a question. What happens if we don't use output load in CMOS circuits? What happens to overshoot/undershoot and circuit delay?

Why does the voltage across a shunt spike then settle?

I'm using a 50 Ohm shunt to measure a current of about 50mA driven by a voltage of 110v 60Hz AC as a zero-crossing square-wave (with a step at the zero-crossing). Using my oscilloscope I can see that the voltage from the supply (an inverter…
