11 / 16 page AN441 Typical examples of inrush current reduction Doc ID 3579 Rev 3 11/16 Figure 10 show an example of Triac switching on a 2200 W universal motor with or without soft start. The difference is very clear, the current reaches a peak current up to 60 A without soft start while it reaches 10 A with soft start. This current reduction has a direct impact in the AC switch maximum junction temperature as shown in Figure 11 with a T1050H Triac. The use of soft start at motor start-up allows: ● Lower junction temperature – Better temperature operation margin leading to increased lifetime for the AC switch – Use of lower AC switch range ● Lower peak load current – Lower load current stress, so appliance reliability increases Figure 11. Junction temperature rise for Triac T1050H for universal motor 124.2 °C Without soft start With soft start 78 °C Time (s) T (°C) j 0 0.8 0.6 0.4 0.2 80 130 120 100 65 T1 j a T2 j a |
