Circuit engineering of the charger for the on-line UPS. Part 51 year ago
And again hello … In total with last New year and with other coming holidays! Time
My good mood
After the analysis of article devoted to a code under STM32 I understood — in vain spent time, level of readers and many commentators as I understood sufficient for independent writing of a code therefore I do not see sense in further analyses. All moments with a code will be limited to the description of algorithm and the detailed flowchart, everyone will be able to write an applet under the MK and though under an arduina. The truth you should not be upset that who wanted to repeat this device in original state — you can always receive a firmware in the form of .hex at me in a pm, and also order already stitched microcontroller at the price of cost of a stone and a postage. On it good news ended...
Now about this part — it will be devoted to the DC-DC transformer 310B-> 48B. That is we consider not all battery charger, namely the transformer. The rectifier and KKM will be separate part since functionally they at me are executed by the separate module on a separate payment.
Topology on which this transformer is constructed (or the power supply unit) — "the slanting bridge". Initially I wanted to leave option of the complete bridge without changes against pry. option, but rather large number of companions passed an opinion on complexity of the N-bridge, its high cost and low recurrence at such capacities. I thought and decided to apply my once favourite topology which appreciated its high recurrence. On topology of "the slanting bridge", by the way, many welding inverters with currents to 200-250A are constructed. Considering that at this stage on work I project an automatic welding semiautomatic device, in addition it is twice interesting to drive such solution.
And so — went....
