While debugging a mid-power push-pull isolated supply (~100W range), I’ve once again hit the classic wall:
Runs fine under light load MOSFET temps shoot up under full load EMI spikes appear around 180-250MHz during pre-compliance checks
The frustrating…
Stephen ,
There is a good reference for loss comparison between inverter mode and pfc mode for a 25kW t type here . this manual doesn't show the equations. The general switching and conduction losses equations for pfc and inverter are similar as shown in…
Part Number: UCC27714 Other Parts Discussed in Thread: UCC28C43 , , CSD19502Q5B
Hi TI Team and Community,
I’m debugging a push-pull converter using the UCC28C43 PWM controller with UCC27714 high-speed gate drivers, aiming for a 100W isolated…
Hi
You can calculate the junction temperature according to the data sheet.
The overheating of the chip may be due to poor heat dissipation design, inaccurate load current evaluation, low efficiency of the switching power supply, and high MOSFET losse…
