The energy conversion capacitor can collect the remained energy of the second inductor so that the energy utilization rate can be enhanced.
Description
technical field [0001] The invention relates to the energy field, in particular to a pulse power supply circuit, a pulse power supply, an electromagnetic emission device and a control method for the pulse power supply circuit. Background technique [0002] Electromagnetic emission is the emerging technology of accelerating objects by electromagnetic force. Compared with traditional emission technology, electromagnetic emission has the advantages of high energy efficiency, high control precision and fast response speed. With the continuous development of science and technology (especially computer control technology and power electronics technology), the practical process of electromagnetic emission technology is constantly accelerating. The electromagnetic emission device is generally composed of a transmitter, a component to be emitted and a pulse power supply. Pulse power supplies generally need to provide megaampere-level pulse current and megajoule-level pulse energy w...
