1. ### How to shut down a wind power plant?

Just curious, how do they shut down those wind power plants given their tall structure? What are the procedures to do it? Thanks.
2. ### How to shut down a hydroelectric power plant generator?

Was cycling near a hydroelectric power plant generator with my sister and she asked me if they can be shut down. I said "Yes, all power plant generators can be shut down". I wasn't sure, so here I am to get some inputs on the safety procedures from AAC readers. Thanks. Any input is appreciated!
3. ### How does a power converter regulate voltage effectively at zero load current?

I am trying to get my head around how power converters regulate the output voltage at no-load conditions. My output pulses from substantially full load ~200mA to substantially no load 0A at frequencies anywhere from 100Hz to 100kHz. My question is quite clear already but, how exactly does a...
4. ### Confused over an easy plot about inductor current

Need some insight about a plot found in the Fundamentals of power electronics second edition book. I don't really understand why it is written like this. Left side $$\frac{I}{V_{g}/R}$$ can be rewritten to $$\frac{1}{D'^{2}}$$ so it is basically "just" duty cycle. The book states that the...
5. ### CRS Robot & C500C Wiring

Hi all, I need a little help interpreting this schematic and doing some wiring for the System Input/Output plug that connects to the rear of the C500C CRS Robot Controller. My goal is to get the plug hooked up to an Opto22 R1 Controller. I'm guessing I'll have to use SNAP-ODC5 modules. If I...
6. ### MATLAB simulation of pulse forming networking using VINPFN

Hi, I am trying to use a set of open source scripts called VINPFN to simulate a type 'B' pulse forming network. An enhanced dialog input box is concurrently required to input various parameters of the network. The scripts are available on mathworks.com and the links for them are listed below...
7. ### Power Supply and Reference Points

Hey folks. I’ve been working on a home project involving a low power AC/DC converter based on the power integrations ref (https://www.mouser.com/datasheet/2/328/rdr623-1487555.pdf). There were some minor changes, I added a current limiter to keep to spec, and in addition the circuitry has a...
8. ### Solar PV Eco Water Heating Open Source Hardware Project/Proposal

I think there is a gap in the market for a new electronic device. The device should power a simple resistive water heating element using the energy from a solar PV array. This will allow for cost-effective and environmentally sound water heating. The device will use maximum power point...
9. ### 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...
