Question 10.7: The voltage and current at the maximum power point in a 200 ...
The voltage and current at the maximum power point in a 200 W solar panel are listed in Table 10.5, along with the maximum power for various level of solar insolation.
Calculate the internal resistance of the panel for each level of solar power, the duty cycle of the buck converter for impedance matching with a load resistance of 8 Ω operating at 20 kHz. Calculate the minimum inductance for continuous conduction.
Table 10.5 Parameters under different load conditions | |||
Insolation (W/m²) | V_{P} (V) | I_{P} (A) | Maximum output power (W) |
800 | 41.3 | 4.1 | 169 |
600 | 41.4 | 3.1 | 128 |
400 | 41.6 | 2.0 | 83.2 |
200 | 41.6 | 1.0 | 41.6 |
