Fully handmade DIY 48V-2500W pure sine wave inverter

There are several reasons for choosing a 48V inverter , such as small current, very good stability, low temperature, no damage to the battery and extended battery life, etc. Some netizens think that 48V power supply is difficult to find, but I don't think so. Many electric vehicles are 48V, just take it out, or you can use 4 12V motorcycle batteries in series. Friends who have electric vehicles might as well buy one so they don't have to worry about power outages. This inverter is basically the same as the usual one, divided into two parts, DC-DC and DC-AC. DC-DC is completed by KA7500+LM324 for overload, undervoltage and overvoltage protection and output PWM pulses! MOS uses IRFP90N20, DC-AC is EG8010+IR2110 output SPWMH bridge also uses IR's bull tube IRFPS43N50K. Let's not talk nonsense, the main picture is as follows!
