Web1 day ago · Brazilian President Luiz Inácio Lula da Silva is in the Chinese financial hub of Shanghai as he looks to boost ties with his country's biggest trade partner. Lula is due to meet with his Chinese counterpart Xi Jinping in Beijing on Friday before concluding his visit to China. The Brazilian government says the sides are expected to sign at least 20 … WebDCM offers higher efficiency than CCM, due to the lack of reverse recovery loss on the diode and a softer turn on of the MOSFET. However, if the duty cycle is too small, then the current that charges the primary inductor will be very high, which lowers the converter’s overall efficiency.

WebJan 3, 2014 · Boost converters can operate in CCM, DCM, or both with major dependencies on the input voltage and load. Calculating the required inductance to guarantee CCM operation involves knowing what input voltage (or duty cycle) to use in the calculation. For designs with a wide input range, use a VIN/VOUT ratio of 2/3 (D = 0.33).
