The RBS3206 macro is an indoor Radio Base Station with one to four carriers and one to six sectors at 20/40 Watt RF output power per carrier. All the boards that I have comes from the middle row in the above picture and unfortunately I did not have any of the diplexers at the top

Second charge experiment with the bank of 35 electrolytic capacitors connected in series. The bank did however not get charged to more than 50% of its maximum holding charge, due to too weak power supply. More results will follow when a new power supply have been made and tested. All discussion about this bank can

I have had the Loneoceans midi2 controller for a while. I just never got around to put it together. Now that I finally have it boxed up, you can see how that was done here. : https://highvoltageforum.net/index.php?topic=114.0 If you want your own MIDI modulator, you can buy it here: http://loneoceans.com/labs/sales/midi2/. Here are 4 videos I

With the snubber capacitor calculator, you can calculate the needed snubber capacitance. The correct value is needed in order to protect your inverters IGBT/MOSFETs. Protect them from too high switching transients, depending on your busbar layout and stray inductance.
