#CMT# #/CMT# The circuit (2) has a variable duty cycle chopping circuit (11) including an input terminal (9) connected to an electric power source (3). An output circuit (14) is connected via an adjustable dimension switch (17) i.e. P-type metal oxide semiconductor transistor, to an output terminal (19) of the chopping circuit. A control circuit (51) controls duty cycle of the chopping circuit and dimension of the switch and an adjustable dimension chopping switch (13) i.e. N-type metal oxide semiconductor transistor, based on power delivered by the power source. #CMT#USE : #/CMT# Direct current-direct current chopper converter circuit for use with an electric power source e.g. photovoltaic cell such as photovoltaic solar cell, thermoelectric element or wind turbine, that delivers power with high fluctuations, to an electronic system (all claimed) i.e. autonomous sensor. #CMT#ADVANTAGE : #/CMT# The configuration of the converter circuit enables reducing the losses of the converter circuit, and optimizes the recovery of energy, while permitting reduction of size of a photovoltaic generator or wind turbine, and an emergency accumulator such as emergency battery or supercapacitor, thus reducing the encumbrance of the system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic circuit diagram of an electronic system with a converter circuit. 2 : Direct current-direct current chopper converter circuit 3 : Electric power source 9 : Input terminal 11 : Variable duty cycle chopping circuit 13 : Adjustable dimension chopping switch 14 : Output circuit 17 : Adjustable dimension switch 19 : Output terminal 51 : Control circuit. |
