Title: ELECTRICAL APPARATUS
Abstract:
In a power feed system for supplying A/C power to an electrical apparatus (40), a capacitor (10) connects to a power grid (30) via a bidirectional DC/AC converter (20). When the capacitor (10) discharges, the bidirectional DC/AC converter (20) performs a power conversion operation on the basis of the value of an alternating current (Iac) as detected by an alternating current detection unit (50) so that the alternating current (Iac) becomes zero. The electrical apparatus (40) is provided with a load unit that operates by receiving power supplied from the bidirectional DC/AC converter (20), and a power adjusting unit for gradually decreasing the power consumed by the load unit when the output of the load unit is stopped or reduced.
