Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2016025817
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power transmission device capable of stabilizing a circuit operation by suppressing the influence of a switching noise.SOLUTION: A power transmission device is connected between an AC wiring system connected to an AC power source and a DC power source, and transmits an electric power to the AC wiring system from the DC power source. The power transmission device constructs: an AC power source voltage signal forming means 10; electric power converting means; a DC voltage converting part; a switching element 11; and a switch opening/closing signal generating means 12. The switch opening/closing signal generating means 12 includes: a control signal generating part 14 generating a control signal formed by a pulse signal; and a pulse width determination part 15 generating delay signal that rising of the control signal is delay due to an input of the control signal, and setting the control signal as the switch opening/closing signal by falling the control signal when the delay signal becomes a value corresponding to the voltage of AC power source voltage signal.SELECTED DRAWING: Figure 2
