摘要： A power control device receiving supply of power from a power source, the power control device including: a power accumulator accumulating a part of power from the power source; a first voltage converter receiving power from the power source and the power accumulator, performing voltage conversion to a first target voltage, and supplying power with the first target voltage to a first load; a second voltage converter receiving power from the first voltage converter, performing voltage conversion to a second target voltage, and supplying power with the second target voltage to a second load; a power source monitor monitoring power from the power source; and a power controller lowering the first target voltage to a level that the second voltage converter is capable of converting to the second target voltage when the power source monitor detects that the supply of power from the power source has stopped.

摘要： A phase control device includes: at least one switching element connected to an AC power source, the switching element being capable of: turning on and off at specified timings; delivering AC power to a load upon turn-on and cutting it off upon turn-off; and keeping an on-time from the start to the end of turn-on and an off-time from the start to the end of turn-off, the on-time and off-time being variable; a timing setting portion that sets a turn-on and turn-off timing for turning on and off the switching element; a judgment portion that judges whether or not the turn-on and turn-off timing are on at a phase within a first or second phase range; and a processor that starts turning on and off the switching element at the turn-on and turn-off timing, the processor being capable of adjusting the on-time and off-time depending on the judgment result.
