the car has become the main means of transportation now, and its safety is of great concern to every owner. the electromagnetic disturbance generated by the normal operation of the vehicle will lead to the reduction of the functions of various on-board electronic products, short-term failures and even permanent damage through conduction coupling. the on-board electronic transient interference simulation test system meets the requirements of iso 7637-2 and iso 16750-2 new and old standards, and is the preferred choice for anti-interference testing of various on-board electronic products.
p1 is the transient phenomenon generated when the analog power supply is disconnected from the inductive load. it is applicable to the situation that various duts are directly connected in parallel with the inductive load when they are used on the vehicle; p2a simulates the transient phenomenon caused by the sudden interruption of the current in the device in parallel with the dut due to the inductance of the harness. the on-board electronic transient interference simulator rv p1p2a meets the latest requirements of iso-7637-2 and gb/t21437.
p2b simulates the transient phenomenon when the dc motor acts as a generator and the ignition switch is disconnected; p4 simulates the reduction of power supply voltage when the starting motor circuit of internal combustion engine is energized. the on-board electronic transient interference simulator rv p2bp4 meets the new requirements of iso 7637-2 and gb/t21437.
p3a and p3b simulate the transient phenomenon caused by the switching process. the characteristics of these transient phenomena are affected by the distributed capacitance and distributed inductance of the harness. the on-board electronic transient interference simulator rv p3 meets the new requirements of iso 7637-2 and gb/t21437.
the automobile electronic interference simulator simulates the transient generated when the alternator is generating charging current while the battery is disconnected (power loss state), and there are still other loads on the generator circuit. the on-board electronic transient interference simulator rv p5 meets the new requirements of iso 16750 and gb/t21437.
the fault simulator of on-board electronic power supply simulates the starting, opening and closing of vehicles; changes or abnormal conditions in the on / off state of electronic devices or in the charge / discharge state of batteries, including multiple tests such as superimposed ac voltage, voltage sag, voltage startup, etc., are ideal interference sources for evaluating the power failure immunity of on-board electronic equipment. the on-board electronic power failure simulator rv 16750 meets the new requirements of iso 16750-2.
