Development trend of portable outdoor energy storage power supply

With the rapid development of the energy storage power supply market, sine wave inverters are widely used in outdoor activities, mobile office, outdoor camping, medical rescue, power supply for vehicular tools, etc., to meet various needs of power shortage.
Sine-wave inverter, the original sine wave inverter needs these protection designs to be safer:
The short circuit protection function refers to the protection that can ensure that the power supply can be cut off quickly and reliably after the short circuit fault occurs in the electrical circuit, so as to prevent the electrical equipment from being damaged by the impact of the short circuit current.
Overcurrent protection function refers to the current protection module of the equipment. When the current exceeds the set current, the equipment will automatically power off to protect the equipment. For example, the USB interface of the main board CPU generally has USB overcurrent protection to protect the main board from burning.
Overpower protection function: when the load is under power supply overpressure, or the secondary load has short circuit overcurrent and other faults exceeding the actual power, the overload protection circuit in the circuit cuts off the main power supply through the feedback circuit action to protect the circuit and load. Make the fault no longer expand.
Under-voltage protection function When the line voltage is reduced to the critical voltage, the action to protect the electrical equipment is called under-voltage protection. Its main task is to prevent the equipment from burning due to overload.
Over-temperature protection function refers to that when the temperature exceeds the flip threshold, the potential at the negative end of the comparator will drop to lower than the potential at the positive end VREF2, and the comparator will output a high level, so as to turn off the power switch device and prevent the chip from burning.
Overcharge protection function. When not in use, we also need to charge the emergency starting power supply of the car. When the power supply is fully charged and the circuit has not been cut off, the power supply will automatically start the overcharge protection function and will not be charged. It can protect the battery and prolong the use of the product.
