Boost regulators are more difficult to design than buck regulators, regardless of whether we control the output voltage or the output current. The average inductor current in a continuous conduction mode (CCM) boost converter is equal to the load current (LED current) multiplied by 1/(1 - D)...

Note boost::size(a) == 0u is equivalent to boost::empty(a). Complexity guarantees boost::size(a) is at most amortized linear time. Invariants Range size boost::size(a) is equal to the distance from boost::be- gin(a) to boost::end(a). See also implementation of metafunctions ...
std::cout << "The result is: " << result << '\n'; } 运行这段程序,可能产生以下输出: The result is: 30 或者产生以下输出: The result is: 27 不使用分组的方法就无法保证正确的行为。我们需要确保double_slot总是在plus_slot之前被调用。这就要求我们要指定double_slot属于一个顺序在plus_slot所...
