DC-AC Automatic Voltage Regulator and Boiler having DC-AC Automatic Voltage Regulator

摘要

The present invention relates to a DC-AC automatic voltage regulator and a boiler including the same. According to one aspect of the present invention, a first switch connecting one side of the input power source and one side of the second inductor, a second switch connecting one side of the input power source and one side of the first inductor, the other side of the input power source and the second inductor a third switch connecting the other side of the , and a fourth switch connecting the other side of the input power and the other side of the first inductor, wherein the input power is DC power, and the other side of the load is connected to the other side of the input power, As the first to fourth switches are turned on or off, a DC-AC automatic voltage regulator operating in a boost mode or a reduced mode (buck mode) is disclosed. According to the present invention, since the low voltage AC is generated using the low voltage DC, it is more stable than the circuit using the high voltage AC and the number of failure variables is reduced.
