The purpose of the invention is to increase the K1SC and to maintain the speed.

The drawing shows a functional heme of the proposed source. Jq

A pulsed power supply source consists of a key regulator 1, formed by a control key 2 and a .LG filter 3, a first and a second current 4 and 5, a continuous regulator 6 with a feedback node 7, an amplifier 8 feedback, the measuring element 9, the second adder 10, the sample-storage node 11, the divider 1 2 and the first adder 13. The key controller 1 formed by the control key 2 and the DLC filter 3 is connected to a continuous regulator the torus 6 through the first sensor 4 current-. The first current sensor 4 and the output of the continuous 25 controller 6 through the measuring element 9 and the amplifier 8 are connected to the input of the control switch 2; The inputs of the sampling-storage device 11 are connected to the output of the amplifier 8 and the connection point of the AOR, the diode and the throttles of the DLC filter 3, and its output is connected to the auxiliary input of the measuring element 9, to the second auxiliary input of which the output of the DELITEL 12 is connected To the input of the divider 12, the first adder 13 is connected, to the inputs of which the outputs of the first and second sensors 4 and 5 of the current are connected, and to the second turn 40 - the output of the second adder 10, to the inputs of which the choke of the DLC filter 3 is connected.

Pulse power supply operates as follows. ds

The control key 2 clocks the incoming supply voltage at its input to the BSC filter 3. The first measuring element 9, taking into account the instantaneous values of the load current and voltage

bias on the linear regulator, controls the on and off of the control key 2 so that the linear regulator 6 is in active mode of operation. The control method can be identical to that proposed in the prototype, and different from it.

blunt to the second adder 10 and subtracted, the result is divided by the signal c. the output of the first adder 13, which subtracts from the load current (first sensor 4 current) current droplets DLC-filter 3 (second sensor 5 current).

Sampling-storage unit 11 measures and stores the resorption time of the transistor, converted into a proportional voltage, which is compared with the result of dividing taking into account the instantaneous values of the load current and the bias voltage of the continuous regulator 6 in the first measuring element 9, i.e. takes into account variations in supply and load voltages, as well as load current.

Accounting for the instantaneous values of currents and voltages of the DLC-filter 3 allows you to know in advance the moment when the control key .2 should be turned off, and the value of the resorption time makes it possible to give a closing signal at the right time. In addition, taking into account the instantaneous values of currents and voltages allows to reduce the effect of changes in the output voltage and, consequently, reduce ripples and increase efficiency.

If the resorption time is known, then node 11 is excluded from the scheme. storage samples, which simplifies the design.
