Abstract
An electric circuit arrangement and a method for generating electric current pulses to a load, the electric circuit arrangement including a switch and a current source in series connection with the load; wherein the switch is arranged to operate in at least an on state and an off state, thereby selectively connecting or disconnecting the current source to or from the load so as to generate the electric current pulses. With such architecture, the circuit performs with a better efficiency than a cascaded architecture.
Claims28
An electric circuit arrangement for generating electric current pulse to a load, comprising a switch and a current source, wherein the switch, the current source and the load are in series connection with a DC source arranged to power the load;
- wherein the switch is arranged to operate in at least an on state and an off state, thereby selectively connects or disconnect the current source to or from the load so as to generate the electric current pulses;
- wherein the current source is operable to compensate a power difference between the DC source and the load, by absorbing electric power from the DC source when an instantaneous power provided by the DC source exceed a load power required by the load, and providing the absorbed electric power to the load when the instantaneous power provided by the DC source is less than the load power required by the load.
A method for generating electric current pulses to a load, comprising the step of manipulating a switch and a current source in series connection with the load and a DC source;
- wherein the switch is arranged to operate in at least an on state and an off state, thereby selectively connects or disconnect the current source to or from the load so as to generate the electric current pulses;
- wherein the current source is operable to compensate a power difference between the DC source and the load, by absorbing electric power from the DC source when an instantaneous power provided by the DC source exceed a load power required by the load, and providing the absorbed electric power to the load when the instantaneous power provided by the DC source is less than the load power required by the load.
