Title: Constant-voltage charger
Inventor: SATO TERUO
IPC: H02J7/10
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To minimize heating from a series control element by cutting off the series control element for a specified period of time immediately after power-on using a power-on detecting section, and detecting short-circuit between charging terminals through a voltage sensor. SOLUTION: When a charger is connected to a commercial power supply 1 with its charging terminals 40, 41 short-circuited with each other, the voltage of a direct-current power supply 60 is sharply increased. A power-on detecting section 10 is fed with this abrupt variation in voltage, and short-circuits the output of an error amplifier 7 to the negative line of the charger for a specified period of time. As a result, a pre-amplifier 9 controlled through the output of the error amplifier 7 interrupts a current passed through a series control element 6. At this time, a direct-current power supply 60 is virtually brought under no load, and the output of the direct-current power supply 60 is maximized.  Since the charging terminals 40, 41 are in a state close to short circuit, the potential difference between the voltage of the direct-current power supply 60 and the voltage of the positive charging terminal 40 exceeds a predetermined value. Therefore, a voltage sensor 8 switches on, and the pre-amplifier 9 interrupts a current passed through the series control element 6.
