Why rubber shoes (or crocs) don't prevent electric shock
In this video, we take a look at the curious case of getting zapped while seeminly isolated from the ground. It turns out in some cases, electricity doesn't need a conductive path.

Home made grid-tie inverter (not even all that sketchy)

A few years ago, I built a crude DIY grid-tie inverter. Its performance however, wasn't good enough, so I decided to have another go at it. Here's a link to the circuit diagram/code for this project: akiotv.nl/warehouse_data/grid_tie_inverterV2.zip (AKIO TV) MMXXIV actual_akiotv

Before connecting them directly the first time, you could use a resistor between them to limit the current.

    Hi, will a 6V 208Ah battery and 5- 6V 225Ah battery connected in series for 36V be a big problem? I'm having trouble getting a direct replacement for a bad battery on my golf cart, and I don't really want the expense of having to by all new batteries. I know you said capacities should be the same in series, but I'm thinking the older 225Ah batteries may have some degradation any way. Thanks

    I have to object. In Germany, grid tide inverters must have a double shutdown in the event of a fault. On the one hand, the mains voltage is monitored and the H bridge is switched off via software. On the other hand, a relay must be added that separates the inverter from the mains voltage. A large Chinese manufacturer ran into problems because he replaced the relay with a wire bridge. The Chinese decided to provide customers with an additional relay free of charge. This saved the manufacturer's reputation.

    Hi, I want to create my own SRM based on your videos (they are a great inspiration), but I have some questions. What is the purpose of D3, D2, and D1? Are these diodes preventing reverse current? What is the nominal power rating of the resistors before these diodes? How can I determine the current my motor will need? I want to use the DRV8300 to drive the MOSFETs. Is it a good choice, or do you recommend other MOSFET drivers? Are C1, C2, and C3 capacitors needed, or can I use one larger capacitor at the input?

      @AKIOTV 26 дней назад

      @@kotrinio7868 C1, 2 and 3 are bootstrap capacitors to drive the top mosfets. They are charged through D1, 2 and 3. The drive voltage of the high side mosfets needs to be higher than the supply voltage, or thr mosfets will not turn on. Therefore, a capacitor (say C1) is charged up to the supply voltage (24v), then, when Q10 and Q6 are opened, C1 is disconnected from ground and instead connected to the source of the mosfet, pushing the voltage on the top of C1 above the supply voltage so that the mosfet can turn on. If diode D1 wasn't there, this wouldn't happen, the capacitor would immediately discharge. The need for a bootstrapping circuit like this could be eliminated by using P-mosfets for the high side instead.
