CONVERTER DEVICE

摘要

A converter, for feeding a load via an inductor with a current having a controlled intensity between a maximum and a minimum level, includes a switch to permit or prevent, respectively, current towards said inductor, a first current sensor sensitive to the current flowing through switch when the switch is on, a second current sensor sensitive to the current flowing through said inductor when the switch is off, drive circuitry to turn the switch off and on upon receiving a first and a second logic signal, respectively, and comparison circuitry coupled to the first and the second current sensors to generate first and the second logic signals when, respectively: the current intensity detected by the first current sensor is offset a given amount with respect to the maximum level, and the current intensity detected by the second current sensor is offset a given amount with respect to the minimum level.

1. A converter for feeding a load via an inductor with a current having a controlled intensity between a maximum level and a minimum level, the converter comprising:
a switch switcheable on and off to permit or prevent, respectively, feeding of current towards said inductor, a first current sensor sensitive to the current flowing through said switch when said switch is on, second current sensor sensitive to the current flowing through said inductor when said switch is off, drive circuitry of said switch to turn said switch off and on upon receiving a first and a second logic signal, respectively, and comparison circuitry coupled to said first and second current sensors to generate first and a second logic signals when, respectively: the current intensity detected by said first current sensor is offset of a given amount with respect to said maximum level, and the current intensity detected by said second current sensor is offset of a given amount with respect to said minimum level.
