ABSTRACT:Power device, as a typical example of power electronic devices, plays a vital role in related equipment of the smart grid. To meet the requirements of gate driving of the insulated gate device (insulated-gate bipolar transistor (IGBT), metal-oxide-semiconductor field-effect transistor (MOSFET) for the dynamic parameters measurement in the smart grid, the pulse logic signal generator is designed based on STC89C52 microcontroller.According to the requirements of the measurement, the generator can provide single pulse or double pulse square waves, and for actual test condition, the pulse width and spacing can be adjusted .Specific pulse signal type (single or dual pulse) and pulse width can be adjusted, and the precision can reach to 1μs and the precision of displaying is less than 0.02μs. At the same time, according to the need, either single mode or periodic mode can be set up. The test results show that the pulse generator is designed to have high output voltage stability, high accuracy and has very good practical value.
