Design and application of IR2110 driver chip in photovoltaic inverter circuit

IR2110 is a bridge driver integrated circuit chip of IR company . It adopts highly integrated level conversion technology, which greatly simplifies the control requirements of logic circuits for power devices and improves the reliability of driving circuits. For the single-phase photovoltaic inverter circuit with ZCS link designed by me, there are 6 IGBTs, which can be driven by only 3 chips. The soft switching and inversion functions are realized through dsp2812 control. At the same time, it only needs to provide 3.3 V and 12 V reference voltage to work. In engineering, the volume of control transformer and the number of power supplies are greatly reduced, the product cost is reduced, and the system reliability is improved.
