Problems solved by technology

If an anti-surge circuit and an anti-single event latch circuit are connected in series at the input end of the power supply of the equipment, a large voltage drop will occur in the power supply, which will affect the normal use of the equipment.
Therefore, most of the current anti-sin

Abstract

The invention discloses a circuit module capable of preventing surge and single event latchup for on-satellite equipment. The circuit module comprises a power switch K1, a diode D1, resistors R1, R2,R3, R4, R5, R6 and R7, triodes Q1 and Q2, capacitors C1 and C2 and a power field effect transistor Q3. The circuit module integrates an anti-surge circuit and a single event latchup preventing circuitto enable the circuit module to have an anti-surge function and a single event latchup prevention function simultaneously, thereby effectively reducing voltage drop of the power end, improving equipment efficiency, reducing equipment power consumption and improving global stability of the system.

Description

technical field [0001] The invention relates to the technical field of protection circuits in satellite equipment, in particular to a surge-proof and single-event latch-proof circuit module for satellite equipment. Background technique [0002] At present, anti-surge design is widely used in the circuits of on-board equipment. The moment the equipment on the star is turned on, a large current will be generated. This current is called a surge current. The surge current is generally more than ten times higher than the normal operating current, or even larger. The appearance of the surge current will generate a large magnetic field and electric field. Interference, affect the normal work of other equipment. Therefore, the equipment on the star needs to add an anti-surge circuit at the input end of the DC power supply. The anti-surge circuit consists of a high-power FET and a resistance-capacitance delay circuit. When the device is turned on, the high-power FET can withstand l...
