Abstract:
A water area apparatus according to one aspect of embodiments includes: a first device; a second device whose power consumption is smaller than that of the first device; a Power Factor Correction (PFC) circuit that is connected to an Alternating-Current power supply, reduces harmonic current, and steps up a voltage to output the stepped-up voltage; and a regulator that is connected to the PFC circuit and steps down a voltage to obtain a constant voltage, wherein the voltage stepped up by the PFC circuit is applied to the first device, and the voltage stepped down by the regulator is applied to the second device.
