Hello everyone,

Currently i need a DC to AC inverter that will have an output of frequency 100khz.
The input is 12v DC & 0.5A.
This is for wireless power transfer purpose.

The flow diagram :
12 VDC 0.5a > inverter 100khz > tx coil || rx coil > rectifier > load (12v 0.5a max)


1) May i know the recommendation of the MOSFET model that is suitable for this ? pwm will be generated by arduino.

2) Also is there a built H-bridge thingy that i can buy offshelves and just program the frequency ? if so please give me a recommendation of the model.

Thankyou. :smile:
 

Can you post the schematic diagram of your circuit ?

You can you use ...
a) A Full H-Bridge or
b) A Half H-Bridge or
c) A single MOSFET

Are you designing a LC Resonant circuit?

This example pre-built device, does come with a 12 Volt 700ma (output) option.
Wireless-Charging

Some units are only 40% efficient.
So, the input current would be 1.75 Amps (input) = 700 ma (output) / 40%

Hi, thanks, im looking at option "a". hence i need recommendation for the Mosfet model that can meet the specs :grin:
 



Hi, i'm wondering if the "IMS-2B" will work ??

its specs is :
Details
Rated voltage: 3V-15V
Rated current: 50 A
peak current: 110 A
switching frequency: 1 K to 200 kHz
