    How does Noise is effected by inverter switch technique, output current, modulation index?

    How is the noise on the supply side effected by DC bus voltage, rise and fall (di/dt, dV/dt), switching frequency and techniques, modulation index and load current? Is there any formula or analysis we can do? Analytically?

    Alternative open frame power supply solutions?

    After my initial newbie post, I have decided I want to use an open frame power supply for my project. (Low power fan heater) I have looked at a few and I'm not sure whether I am either looking incorrectly or what I am looking for is just out of my price range and a cheaper option doesn't exist...

    High Current negative voltage from a positive one

    Hi, For a project I am working on I need to generate a negative voltage from a single positive one. More precisely, I need -18V from +18V with at least 1A. For the first prototype, I am using an LT1054 (http://www.ti.com/lit/ds/symlink/lt1054.pdf) powered @+15V and everithing works as...

    MEAN WELL TS-1000 Inverter not working

    Hi, I am using a MEAN WELL TS-1000 inverter. Currently the inverter got an issue such that when the inverter is switch on it will automatically turn off within less than 5 seconds and then it starts to blink the status LED in orange color. If anyone has an experience with this kind of inverter...

    Variable Frequency Drive - Optimum lathe VFD problems - irregular, stuttering speed

    Hi Folks, this is a preliminary, looking for anyone who has come across a similar issue before, before I start trying to reverse engineer the PCB etc. (Which I'm not a big fan of as it would really need live testing.) I have a 230V AC 50Hz (single phase) Optimum Lathe, which has a variable...

    LCL Filter Plant Control

    Hi everyone! I don't know if this is the place to ask Control Theory related questions, but it's for modelling a power electronics circuit so I thought I could at least try. I have to design a grid connected inverter in Simulink using the PLECS toolbox and I ran into some problems when designing...

    Can I connect Solar and Wind DC energy to the same battery bank?

    Hi there, I am looking at installing a solar and wind energy system on a house. The solar panels produce DC and the wind AC but the winds AC is passed through a controller which converts it to either 24 or 48VDc. Therefore both solar and wind will be producing DC. I intend for this to be an...
