Inductive Switching Measurements 4 Figure 8. Peak–Reverse Current Motorola Bipolar Power Transistor Device Data 6 SWITCHING TIMES NOTE In resistive switching circuits, rise, fall, and storage times have been defined and apply to both current and voltage waveforms since they are in phase. However, for inductive loads which are common to SWITCHMODE power supplies and hammer drivers, current and voltage waveforms are not in phase. Therefore, separate measurements must be made on each waveform to determine the total switching time. For this reason, the following new terms have been defined. tsv = Voltage Storage Time, 90% IB1 to 10% Vclamp trv = Voltage Rise Time, 10 – 90% Vclamp tfi = Current Fall Time, 90 – 10% IC tti = Current Tail, 10 – 2% IC tc = Crossover Time, 10% Vclamp to 10% IC An enlarged portion of the inductive switching waveforms is shown in Figure 7 to aid in the visual identity of these terms. For the designer, there is minimal switching loss during storage time and the predominant switching power losses occur during the crossover interval and can be obtained using the standard equation from AN–222: PSWT = 1/2 VCCIC(tc) f In general, trv + tfi tc. However, at lower test currents this relationship may not be valid. As is common with most switching transistors, resistive switching is specified at 25_C and has become a benchmark for designers. However, for designers of high frequency converter circuits, the user oriented specifications which make this a “SWITCHMODE” transistor are the inductive switching speeds (tc and tsv) which are guaranteed at 100_C. ] INDUCTIVE SWITCHING 1 5 3 0.5 2 t, TIME ( µs) t, TIME ( µs) TC = 25°C 1 0.7 TC = 100°C 0.3 TC = 100°C 0.5 TC = 100°C TC = 25°C 0.2 0.1 TC = 25°C 0.05 0.3 0.03 0.2 βf = 5 0.1 βf = 5 10 20 5 3 7 IC, COLLECTOR CURRENT (AMPS) 2 1 tc tfi 0.02 30 0.01 50 1 2 Figure 9.

Safe operating area curves indicate IC – VCE limits of the transistor that must be observed for reliable operation; i.e., the transistor must not be subjected to greater dissipation than the curves indicate. The data of Figure 12 is based on TC = 25_C; TJ(pk) is variable depending on power level. Second breakdown pulse limits are valid for duty cycles to 10% but must be derated when TC 25_C. Second breakdown limitations do not derate the same as thermal limitations. Allowable current at the voltages shown on Figure 12 may be found at any case temperature by using the appropriate curve on Figure 14. TJ(pk) may be calculated from the data in Figure 11. At high case temperatures, thermal limitations will reduce the power that can be handled to values less than the limitations imposed by second breakdown. 10 20 100 200 500 1000 5 50 VCE, COLLECTOR–EMITTER VOLTAGE (VOLTS) Figure 12.

Under these conditions the collector voltage must be held to a safe level at or below a specific value of collector current. This can be accomplished by several means such as active clamping, RC snubbing, load line shaping, etc. The safe level for these devices is specified as Reverse Bias Safe Operating Area and represents the voltage current conditions during reverse biased turn–off. This rating is verified under clamped conditions so that the device is never subjected to an avalanche mode. Figure 13 gives RBSOA characteristics. FIgure 13.

Rated Overload Safe Operating Area (OLSOA) OLSOA applies when maximum collector current is limited and known. A good example is a circuit where an inductor is inserted between the transistor and the bus, which limits the rate of rise of collector current to a known value. If the transistor is then turned off within a specified amount of time, the magnitude of collector current is also known. Maximum allowable collector–emitter voltage versus collector current is plotted for several pulse widths. (Pulse width is defined as the time lag between the fault condition and the removal of base drive.) Storage time of the transistor has been factored into the curve. Therefore, with bus voltage and maximum collector current known, Figure 16 defines the maximum time which can be allowed for fault detection and shutdown of base drive. OLSOA is measured in a common–base circuit (Figure 18) which allows precise definition of collector–emitter voltage and collector current. This is the same circuit that is used to measure forward–bias safe operating area. 5 IC (AMP) 4 RBE = 100 Ω 3 500 µF 500 V RBE = 2.2 Ω RBE = 10 Ω 2 1 Notes: • VCE = VCC + VBE • Adjust pulsed current source for desired IC, tp RBE = 0 0 2 4 6 dV/dt (KV/µs) Figure 17.
