In one application, a 12V battery is to be used to power up six power LEDs connected as shown in Figure 3. The LED parameter is given Table 1. Using the rated parameters as the basis calculation, design a suitable DC-DC converter for this application whereby the inductor current variation must not exceed 50% of the output current whereas the output voltage ripple must be less than 5%. The system uses 200 kHz switching frequency Vo...

Edgar Kaskla argues that, in California, economic power equals political power. To the extent that most of our political leaders are economically wealthy and well-connected, is governance by an economic elite in CA inevitable? Are there ways that this political dynamic could be challenged, or undermined?
