Simple Resonant Inverter, 100 kHz, 100W

johnyradio — Fri, 19 May 2023 22:26:08 GMT

I need to make a Resonant Inverter, with AC output.

Application is an AC power supply
Topology: LLC or other
Input: 12V to 24V DC
No DC output
100 kHz
100W
0 to 20A continuous
constant voltage
0 to 5V
Inductive load for galvanic isolation
pure sine
soft-switched
1/2 bridge or 1/4 bridge

Our load uses AC directly from the secondary of the load-trafo. We will not rectify or filter the secondaries of those load-inductors.

What NXP parts are recommended? Seeking FET's, gate driver, controller, etc

Dear John,

inverter concept please check this link. You can find there a block diagram with recommended components. We do not have any FETs in our portfolio. For the recommended Gate Drivers, IGBTs or SIC FETs are recommended.

Please also check this link for EV Power Inverter Control Reference Platform Gen 2.

With Best Regards,

Jozef

Hello,
Thank you for your recommendations!

But there are some issues:

- Those are heavy-duty EV devices. Ours is a mobile consumer device, so our form factor is small and light.

- Our power requirements are significantly lower.

- We don't need DC output or rectification. Our load uses AC directly from the secondary of the load-trafo. We will not rectify or filter the secondary.

Any ideas?
Thx!

Hello John,

unfortunately we do not have any other inverters in our portfolio. Only the three heavy duty for automotive applications. GD31xx.

I apologize for inconvenience.

With Best Regards,

Jozef
