Hi everyone , today i show what LS600h inverter contains.
This inverter was bay for my 4wd prius project. in this moment i got stuck with battery choise, but it isn`t for a long time.
In this case i have some time for figure out this inverter.
Inverter has 2 four-lauers PCBs.The bottom PCB is IGBT drivers with power supply for resolver.
The TOP PCB contains two DSP NEC , two-resolvers chips , resolvers sinewaves Amp, current sensor Amp, and some feuatures like dc/dc and 74HCs chips.
We have 10kHz two sinewaves generator (for MG1 ang MG2) with COS-SIN amp thft connected to DSP.
IGBTs have different a conductor cross sectional area, cause MGs have different power capacity.
Now i started altium test project that i`m going to share soon.
