Performance with heatsink at the back with 500 W

As shown in Figure 17, both case temperature readings at the resistor (78°C) and PCB location A (49°C) are higher
than those (64°C and 44°C) with same parts at 420 W in Figure 15 and also higher than the (69°C and 46°C) with
2
D at 420 W in Figure 12. The middle of the heatsink temperature reads 55°C, as shown in Figure 18, and is 5°C
2
higher than that with D parts with 420 W, as shown in Figure 13. The average efficiency with D
shown in Table 6 is 97.0 percent, which is 0.4 percent higher than that with 420 W, shown in Table 4.
