MMSF7P03HD http://onsemi.com 4 power mosfet switching switching behavior is most easily modeled and predicted by recognizing that the power mosfet is charge controlled. the lengths of various switching intervals ( t) are determined by how fast the fet input capacitance can be charged by current from the generator. the published capacitance data is difficult to use for calculating rise and fall because drain?gate capacitance varies greatly with applied voltage. accordingly, gate charge data is used. in most cases, a satisfactory estimate of average input current (i g(av) ) can be made from a rudimentary analysis of the drive circuit so that t = q/i g(av) during the rise and fall time interval when switching a resistive load, v gs remains virtually constant at a level known as the plateau voltage, v sgp . therefore, rise and fall times may be approximated by the following: t r = q 2 x r g /(v gg ? v gsp ) t f = q 2 x r g /v gsp where v gg = the gate drive voltage, which varies from zero to v gg r g = the gate drive resistance and q 2 and v gsp are read from the gate charge curve. during the turn?on and turn?off delay times, gate current is not constant. the simplest calculation uses appropriate values from the capacitance curves in a standard equation for voltage change in an rc network. the equations are: t d(on) = r g c iss in [v gg /(v gg ? v gsp )] t d(off) = r g c iss in (v gg /v gsp ) the capacitance (c iss ) is read from the capacitance curve at a voltage corresponding to the off?state condition when calculating t d(on) and is read at a voltage corresponding to the on?state when calculating t d(off) . at high switching speeds, parasitic circuit elements complicate the analysis. the inductance of the mosfet source lead, inside the package and in the circuit wiring which is common to both the drain and gate current paths, produces a voltage at the source which reduces the gate drive current. the voltage is determined by ldi/dt, but since di/dt is a function of drain current, the mathematical solution is complex. the mosfet output capacitance also complicates the mathematics. and finally, mosfets have finite internal gate resistance which effectively adds to the resistance of the driving source, but the internal resistance is difficult to measure and, consequently, is not specified. the resistive switching time variation versus gate resistance (figure 9) shows how typical switching performance is affected by the parasitic circuit elements. if the parasitics were not present, the slope of the curves would maintain a value of unity regardless of the switching speed. the circuit used to obtain the data is constructed to minimize common inductance in the drain and gate circuit loops and is believed readily achievable with board mounted components. most power electronic loads are inductive; the data in the figure is taken with a resistive load, which approximates an optimally snubbed inductive load. power mosfets may be safely operated into an inductive load; however, snubbing reduces switching losses. figure 7. capacitance variation 10 30 ?10 v ds , drain?to?source voltage (volts) 3500 1000 c, capacitance (pf) 500 0 0 c iss c rss c oss t j = 25 c v gs v ds 20 1500 2000 2500 3000 q2 figure 8. gate?to?source and drain?to?source voltage versus total charge q g , total gate charge (nc) 30 0 3.0 1.0 0 v 5.0 10 15 20 25 2.0 4.0 5.0 gs , gate?to?source voltage (volt s) v gs v d s t j = 25 c i d = 7.0 a v , drain?to?source voltage (volts) 3 0 1 0 0 2 0 q1 q3 40 6.0 7.0 35 qt
