2SK1020 inverter switching

muddasirwaheedmalik · 31st May 2012, 03:45 PM

hi,
2SK1020 is rated at 300W, with switced current of 92A and 30 A continours, i am planning to build power supply for my truck with battery at 24V.

the indented power of amplifier is 4000W (assuming driving 4 subwoofers) , how many 2SK1020 should i be needing for switiching at 24V primary.,

i assumed with losses 200A should be the target , would 4 on each primary side of step up transformer should be enough? someone suggested me 2SC5200 BJT 150W , 30A Ic as a better option? any suggestions please ?

any idea of heat disspiation and heat sinking requirement ?

or any suggestion for IRFP series mosfets ?

IRFP 460 ??? PD 260 W??? 80 A pulsed current

Discard BJT´s, they are power wasters. 2SK1020 are very heavy MOSFET´s. Which topology are you thinking to use?

at the moment i am just concentrating on balanced pull push for the power supply . so how much 2SK1020 would i need to handle 200 A between 24V . ? any suggestions

10 minimum per side, 300 amps I would use. You also may try 70N06.

Can i use Solid state relays for switching ????? 100 A modules ????
Three-phase solid state relay - 100 A | APC6000 series - Anacon Power & Controls like this one????

or an IGBT power module ???? like this

this one is 1100 Watt, 300A

For lower power voltages, IGBT´s are inconvenient because large VCEsat, 1 to 1.5VDC, it is more economical to use MOSFET´s.

i have seen 70N10 and 80N10, very good power and current ratings for small VCE. any suggestions for using them in parallel, i have hand on LOT stock of FUJI 500A, darlington power modules, its rated 2000W with 500 A collector current. may be using 2 of them in parallel will abundant switching power. BTW its available at $15 a piece from a local vendor who breaks down old large UPS/inverters to salvage parts /

its FUJI 1DI500A-030, any suggestions ?
