In this dissertation, PIN diode reverse recovery mechanism is first analyzed in detail, then the PIN diode shutoff physical process is thoroughly investigated. The establishment of a PIN diode reverse recovery process step calculation model is deduced. Some simplified approximations are based on the reverse recovery time calculation formulas. We analyzetwo conditions for PIN diode soft recovery. One isincreasing the minority carrier lifetime inthebaseregion,whichcanincreasethereverserecoverytimeandthesoftnessfactor.
