Abstract
The present invention relates to a beverage preparation device designed for preparing a beverage upon injection of liquid into an ingredients-containing cartridge, the device comprising a pump () coupled between a fluid inlet () and a fluid outlet () for pumping the fluid from said inlet to said outlet, and a processing unit () for the pump () adapted to control an operation of the pump in response to an electrical energy () having a wave form such that the pump is energized only throughout selected half cycles (a,a,a. . . an) of the wave form of the electrical energy, wherein the processing unit () is configured to determine the respective selected half cycles (a,a,a. . . an) in which the pump is energized based on a target ratio (TR) of a target flow rate (FR) and a predefined maximum flow rate of the pump, and based on the calculation of an activation ratio (AR) of the number of past half cycles (A) for which the pump was energized to the number of overall half cycles (B) during a respective beverage preparation process. The present invention further relates to a method for controlling a pump in a beverage preparation device.
