Embodiment
A kind of IGBT drive plate test fixture plate as shown in Figure 1, described test fixture plate comprises fault reseting module, fault locking module, waveform generation module, fault simulation module, power supply module, and described power supply module links to each other with tested single board by fault institute cover half piece, waveform generation module, fault simulation module respectively; Wherein, described fault reseting module links to each other with fault locking module, Board Under Test respectively.
The fault locking module is the module with negative feedback level catch of being built by devices such as an operational amplifier, peripheral resistance and diodes as shown in Figure 2.Its principle of work is: the negative pole incoming level of amplifier is greater than anodal level when normal, amplifier output negative level, the LED display lamp that is connected on amplifier output is in and extinguishes state, when carrying out the fault simulation switch motion, the fault output signal of Board Under Test (IGBT drive plate) has level and carries out flop phenomenon, the negative pole level that causes the amplifier on the frock plate in a very short time less than anodal level, in this very short time, amplifier is output as high level, amplifier output simultaneously feeds back to positive pole by diode and with anodal level catch, make anodal level always greater than the negative pole level, output is in high level state, then the LED display lamp that is connected on output terminal is lighted, judge by the state of observing LED whether the fault output signal of Board Under Test (IGBT drive plate) is correct, just judged also whether drive plate fault output circuit can realize its function.
The voltage-regulation chip of described waveform generation module is SG3525.
Described fault reseting module is that reset switch DRV_RESET sends high level to drive plate fault latch module releasing latch mode as shown in Figure 3.
As Fig. 4-the 1st, the last brachium pontis drive plate topological diagram in the fault analog module, as Fig. 4-the 2nd, the following brachium pontis drive plate topological diagram in the fault analog module.Described fault simulation module comprises the upper and lower bridge arm drive plate, and it is to be connected to the C utmost point of upper and lower bridge arm drive plate and the resistance between the E utmost point by disconnecting respectively, triggers the drive plate failure detector circuit and quotes fault-signal.Power supply module is that the external power supply module is carried out filtering and short-circuit protection circuit composition to the frock plate, is provided+the 5V power supply by the switching of 7805 chips.The acting as of DRV_RESET and FAULT_RESET key in the upper and lower bridge arm: when detecting on the frock plate and judge that the failure response circuit of drive plate can operate as normal, LED lamp D2 on the frock plate can be lighted, fault on the drive plate shows that the LED lamp also can be lighted simultaneously, the tester only need see that D2 is lighted and just can judge that the failure response circuit is not unusual on the drive plate, after D2 is lighted, D2 can't extinguish automatically, then need a reset switch this moment, the fault that key DRV_RESET resets on the frock plate shows the LED lamp, and the fault that key FAULT_RESET resets on the IGBT drive plate shows the LED lamp.
The beneficial effects of the utility model are: this test fixture greatly reduces the test duration of measuring an IGBT drive plate, this frock scheme can be applicable in the IGBT drive plate testing scheme, frock is designed to simply, design is originally low, method of testing is simple, maintenance and operation has all been brought very big optimization, and this scheme possesses the value of extensive popularization.
