White Paper Explains How Power Averaging Cuts Size and Cost for Pulsed Loads

Power Averaging White PaperMany applications, such as pulsed amplifiers and LED lighting, present pulsed loads, where energy is drawn in short bursts. Conventional design approaches demand that the power system is designed around the maximum required power, rather than the average, which increases size, weight and cost.

Power averaging is an approach that uses a power chain designed to supply the average current the load requires, coupled to a large capacitor to deliver the energy in pulses. This technique requires a power supply that can supply a highly capacitive load: something that is not possible with most existing products.

Unlike conventional power supplies, our power components are designed to deliver power efficiently in pulsed load applications. Vicor components such as the DCM do not need external circuitry to ensure stability when used with a large amount of capacitance at their outputs to deliver the peaks in current. Additionally, they will not enter current limit conditions that can also cause significant reductions in system reliability.
