Title:
A converter unit and a method of changing voltage
Document Type and Number:
Japanese Patent JP6010257
Kind Code:
B2
Abstract:
In various examples, a converter unit for converting an input voltage to an output voltage is disclosed. The converter includes input terminals for connecting the converter unit to a voltage supply and for receiving the input voltage from the voltage supply and output terminals for connecting the converter unit to a load for driving the load. A controllable switch is connected to an inductor. The converter unit further includes a current detector for detecting a current of the inductor, a voltage slope detector for detecting a slope of a voltage measured across the controllable switch, and a control unit for controlling the controllable switch on the basis of the inductor current and the voltage slope.
