Abstract

The invention discloses an inductive pulsed power supply which comprises a primary power supply (uS), a main switch (Sop), a first inductor (L1), a second inductor (L2), a first thyristor (T1), a first diode (D1), a second diode (D2), a first capacitor (C1), a first feedback energy thyristor (Tf1), a second feedback energy thyristor (Tf2) and an auxiliary switch (Sfa), wherein a first end of the first inductor is connected with one end of the main switch, a positive pole of the first thyristor and a negative pole of the second diode; a second end of the first inductor is connected with a first end of the second inductor and a negative pole of the first diode; a second end of the second inductor is connected with a negative pole of the first capacitor; a negative pole of the first thyristor is connected with a positive pole of the second diode and a positive pole of the first capacitor; the other end of the main switch is connected with a positive pole of the primary power supply; a positive pole of the first diode is coupled with the negative pole of the first capacitor by a load (Ld); a positive pole of the first feedback energy thyristor is connected with the negative pole of the first capacitor; a negative pole of the first feedback energy thyristor (Tf1) is coupled with the positive pole of the primary power supply by a current limiting resistor (Rf); a positive pole of the second feedback energy thyristor is connected with a negative pole of the primary power supply (uS); a negative pole of the second feedback energy thyristor is connected with the first end of the first inductor; one end of the auxiliary switch is connected with the negative pole of the first capacitor; and the other end of the auxiliary switch is connected with the negative pole of the primary power supply.

Description

technical field [0001] The present invention generally relates to power supply and electromagnetic emission technology, in particular, relates to an inductance pulse power supply which can be used for electromagnetic emission. Background technique [0002] Electromagnetic emission technology is increasingly used in the fields of computer and power electronics. Inductive pulse power supply is a pulse power supply for electromagnetic emission. For example, the capacitor-assisted slow energy conversion meat grinder type inductive energy storage pulse power supply (hereinafter referred to as "STRETCH meat grinder") is a kind of inductor used for electromagnetic emission adopted by the IAT (Institute for Advanced Technology) of the United States. pulsed power supply. [0003] Such as figure 1 As shown, the STRETCH meat grinder contains the primary charging power supply u S , main switch S op , Thyristor T 1 , Diode D 1 and D 2 , the inductance L that constitutes the secon...
