Given: A MOSFET is used in a switching power-pole found in Fig. 2-4a of the text. The operating conditions are as follows: Vin 35V, 6 A, the switching frequency fs 300 kHz, and the duty ratio d 0.4 a) Consider the diode in the power pole. Assuming an offset voltage forward bias model of the free-wheeling diode in which VM 1.2 V, calculate the average forward power loss in the diode HINT: Consider Eq. 2A-1 b) In the diode reverse...
In this lab exercise, you will be doing the following: (A)Estimate the lower and upper 3dB frequencies using dominant pole approximation (B) Calculate the new upper 3dB frequency when a InF capacitance is inserted between the base and emitter (C) Calculate the new upper 3dB frequency when a lnF capacitance is inserted between the base and collector. You need to remove the lnF capacitor inserted between the base and emitter inn part (b). Data sheet readings have been provided for...
