Claim Text:
1. A power booster comprising: an electromagnetic interference (EMI) filter circuit that is configured to convert alternating current (AC) power from among applied AC power and direct current (DC) power, to DC power to be output; a power factor correction (PFC) circuit that is connected to the EMI filter circuit, and configured to boost the DC power input from the EMI filter circuit and stabilize the boosted DC power to output a voltage; a switching mode power supply (SMPS) circuit that is connected to the PFC circuit and applies the DC power input from the EMI filter circuit to a drain of the SMPS circuit through a transformer, the SMPS circuit being capable of generating AC and DC power at the same time; a maximum power point tracking (MPPT) circuit that applies the voltage output from the SMPS circuit between a drain and a source of a switching device; a battery that is charged by receiving power from a solar light energy source connected to the MPPT circuit; and an inverter that uses a synchronization signal of an emergency energy source as an oscillation signal and operates an AC home appliance with the power received in the battery.
