AN1279 offline UPS reference design using the dsPIC® DSC

Cao đẳng - Đại học

... To drive the MOSFETs, a driver must be used that amplifies the signal from the dsPIC DSC device and drives the gates of MOSFETs The gate of a MOSFET behaves like a capacitor The MOSFET drain-to-source ... dissipation on the MOSFETs is then Ptot = Poff + PC, and it is estimated to be 55W per leg Now the MOSFETs can be selected In the reference design, a TO-220 package is used for the MOSFETs Typical ... the MOSFET For the selected MOSFETs: • VGS = ±20V • VGS(TH) = 2-4V • CG(TOT) = 10.7 nF Driver continuous supply current is calculated using Equation 40 Where n is the number of parallel MOSFETs...
