Abstract
A chopped current input electrical energy converter includes at least one conversion module (K1, K2) generating at least one first output signal (Vout1) and one second output signal (Vout2) and including: a transformer (10), an input switching stage (20) controlling the transfer of electrical energy to the transformer (10), and at least one first output stage (30) and one second output stage (40), the first output stage (30) generating the first output signal (Vout1), and the second output stage (40) generating the second output signal (Vout2); the level of the first output signal (Vout1) reflected at a primary winding (11) of the transformer (10) is greater than the level of the second output signal (Vout2) reflected at the primary winding (11) of the transformer (10).
Claims19
A current input chopped electrical energy converter, comprising:
- at least one conversion module generating at least a first output signal and a second output signal;
- a current source connected to the at least one conversion module;
- a transformer comprising at least one primary winding, at least a first secondary winding and a second secondary winding;
- an input switching stage comprising input switch controlling the transfer of electrical energy to said transformer;
- and
- at least a first output stage and a second output stage,
- said first output stage generating the first output signal and comprising a first rectifier, and
- the second output stage generating the second output signal and comprising a second rectifier, a second electrical energy storage capacitor being mounted at an output of said second rectifier, and an output switch actuating said second rectifier,
- wherein a voltage level of the first output signal reflected to said at least one primary winding of the transformer is greater than the voltage level of the second output signal reflected to said at least one primary winding of the transformer so that as long as said input switch is in an open state,
- when said output switch is in an open state, the energy of said current source is transferred into said first electrical energy storage capacitor, and
- when said output switch passes into closed state, the current through said first rectifier decreases and the current through said second rectifier increases, the energy of said current source being shared between said first electrical energy storage capacitor and said second electrical energy storage capacitor,
- until an entirety of the energy of said current source is transferred into said second electrical energy storage capacitor.
