FM-60 Outback aberration amount, if necessary MOSFET.mp4 N-Channel

!±8± FM-60 Outback aberration amount, if necessary MOSFET.mp4 N-Channel

FM-60 Outback driving 60V 60A N-Channel MOSFET 12V auxiliary output deviation in SSR mode. PWM frequency is about 333 Hz load resistance is 2 ohms 400W 29.4V 15A by providing a load. It 's important not MOSFET negative wire emergency stop, positive. The problem is that FM-60's aux output is not isolated to the ground, including a short circuit between the auxiliary battery negative and positive whenever MOSFET, causing the destruction of the MOSFET, 20A fuse because it does not cause fast enough.There are 500 ohm 1/4W resistors on the two auxiliary ports to the transistor gate voltage and reduce current and serve as backup for the purchase. E 3K - 5K MOSFET gate resistance on the ground. 440 mF 35V 0.5V capacitors are there to smooth ripple, ripple, but it's still there. Outback would be nice if provided the opportunity to increase the PWM frequency 4-16 kHz.
