Zero Voltage Switching Modified Boost Converter
Author:
Abstract: Changing the position of the capacitor from the output to the position between the positive output and input connectors, leads to an interesting modification of the traditional Boost converter. The inrush current, when the converter is applied to a stable voltage source e.g. batteries in cars or a battery-buffered DC micro-grid, is suppressed, and the voltage stress across the capacitor is reduced. To reduce the switching losses and to reduce the disturbances caused by fast voltage rise- and fall-times, a zero voltage switching (ZVS) concept is applied and explained step by step and some interesting aspects of the converter are shown. All explanations are supported by calculations and simulations done with LTSpice.
