<p>PROBLEM TO BE SOLVED: To provide an energy conversion device that allows improving energy conversion efficiency.SOLUTION: An energy conversion device 1 includes a power-generating device 101 generating an AC voltage, a rectifier smoothing circuit 102, a DC-DC converter 103, and a delay circuit 104 provided between the rectifier smoothing circuit 102 and the DC-DC converter 103. The DC-DC converter 103 includes a control terminal CN, and is configured to start up when a voltage between the control terminal CN and a ground line of the DC-DC converter 103 exceeds a predetermined start-up voltage. The delay circuit 104 is constituted from a low-pass filter formed only by passive components; the low-pass filter is connected between output terminals of the rectifier smoothing circuit 102, an output terminal of the low-pass filter on a high-potential side is connected to the control terminal CN, and an output terminal of the low-pass filter on a low-potential side is connected to the ground line of the DC-DC converter 103.</p> |
