Abstract
A buck converter has an input circuit for receiving an input signal, a controller connected to and controlling the input circuit, a switch controllable by the controller for switching on/off, a current storage element connected to the input circuit and the switch, and an output voltage storage element connected to the current storage element for connecting in parallel with a load. In a charging phase, the controller causes (a) the input circuit to allow the input signal to pass through for provision to the load via the current storage element and (b) the switch to switch off (becoming an open circuit). In a discharging phase, the controller causes (a) the input circuit to decouple from the input signal and (b) the switch to switch on (become a short circuit), so that (c) current flows within a loop formed by the switch and the current storage element.
