Title:
CONVERTER WITH CONTROL LOOP
Document Type and Number:
WIPO Patent Application WO/2016/020334
Kind Code:
A3
Abstract:
Converters (1) comprise switches (14) for in response to control signals controlling amplitudes of converter output signals and comprise control loops for in response to detections of the amplitudes of the converter output signals producing the control signals. The control loops comprise circuits (21-23) for in response to simple detections of the amplitudes counting a first number of first time-intervals for which the amplitudes are above or below reference amplitudes, for transforming counting results into the control signals having control values, and for in response to the first number of first time-intervals being equal to / larger than a reference number overruling the control values and producing control signals having first or second limit values. Complex detections of the amplitudes are no longer necessary. Simple detectors (3, 4) may detect the amplitudes of the output signals and amplitudes or phases of input signals or rectified versions thereof and produce binary signals destined for binary inputs of micro-controllers (2) comprising the circuits (21-23).
