Abstract
Cars have become the necessary of life. It's time that cars are the necessary of life change into the luxury of life. The owners of cars need more and more electron devices in the open air, such as auto sound, auto DVD, auto fridges, laptops, chargers and kinds of adapters.
Inverter power supplies applied in cars transform from I2V/24V of storage battery DC into 220V AC. ICL8038 DC input voltage into sine wave, and then put Rectifier precision sine wave into buns, After SG3524 SPWM wave generated, IR2110 driver circuit through the final SPWM pulse transformers are used to wave generated by the filter for AC. The inverter power can be used in cars on and boats, it can work with solar battery as well. It supplies the AC to the electrical devices conveniently.
