Title:
POWER CONTROL DEVICE AND INSTRUMENT COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2014/020913
Kind Code:
A1
Abstract:
A power control device comprising a main power source (104), a usage detector (111), a CPU (22) for outputting a command for switching between standby power mode and normal power mode, an auxiliary power source (109), and a transformer (115). The transformer (115) has a primary winding (112), a secondary winding (113), and an auxiliary secondary winding (114) in an auxiliary power source mode switch controller (108) provided with an auxiliary power source control IC (21). In standby power mode, the CPU (22) blocks the supply of commercial power to the main power source (104), and the CPU (22) transitions itself to standby power mode and performs control so that the auxiliary power source control IC (21) repeatedly stops the intermittent driving of the auxiliary power source (109). Standby power can thereby be greatly reduced when the instrument is not being used.
