Abstract
Switching power supply for generating a voltage for a pulsating load (2), in particular for generating a helix voltage for a TWT. The switching power supply is provided with a dc voltage source (1), a buffer (12) from which the load (2) is powered, and switches (3) and a control circuit (5) for regulating the charging of the buffer from the dc voltage source (1), whereby the power supply is provided with a circuit coupled to the dc voltage source (1), which circuit consists of a current source (6), the above-mentioned switches (3) and a primary (9) of a converter (7). The buffer (12) is powered from the secondary (11) of the said converter (7). The control circuit (5) controls the switches (3) by means of a signal which is a function of the rhythm of the pulsating load and the voltage across the buffer.
Claims7
A switching power supply including a dc voltage source for generating a dc voltage for a pulsating load comprising:
- buffer means for powering said load;
- converter means having a primary and a secondary, said secondary connected to the buffer means;
- a constant current source connected to the dc voltage source;
- switch means connected to said constant current source and the primary of said converter means;
- and
- load responsive control means connected to the switch means for selectively connecting said constant current source to the primary of the converter means in response to said pulsating load.
