发明名称 AC-DC power supply device and switching mode power supply device
摘要 Provided is an alternating current (AC) and direct current (DC) power supply device in which normal power and power of a solar cell is used to supply not only AC power but also DC power, particularly, power of a solar cell is first supplied as DC power or is charged in a battery, and after battery charging, residual power is converted to AC power via an inverter so as to replace normal AC power or to transmit AC power to the outside. Accordingly, an SMPS power supply method in which AC and DC power are supplied at the same time may be provided, and moreover, power of a solar cell may be effectively used. As AC power and DC power may be supplied based on normal power, and DC power of a solar cell may be charged in a battery or converted to AC power and supplied, the convenience of supplying AC power and DC power at the same time may be provided, and loss due to conversion between AC and DC power may be minimized. In addition, the use of environment-friendly alternative energy may be facilitated, and power may be efficiently used since power is charged or transmitted to required places so that power may be supplied even in an emergency.
