| 1. A power converter device having a primary-side circuit and a secondary-side circuit, the primary-side circuit being insulated
from the secondary-side circuit, the power converter device comprising:
a voltage monitoring device for monitoring voltage output from the secondary-side circuit, the voltage monitoring device including:
an AC input portion having a first terminal and a second terminal each connected to a first output port and a second output
port of the secondary-side circuit that output alternating current;
a rectifier circuit having a third terminal and fourth terminal for rectifying the alternating current received at the AC
input portion, wherein the rectifier circuit is connected to the first terminal and the second terminal of the AC input portion
via the third terminal and the fourth terminal of the rectifier circuit, respectively; and
a detection circuit for detecting output voltage of the rectifier circuit and generating a control signal that controls the
primary-side circuit,
wherein the first terminal of the AC input portion and the first output port of the secondary-side circuit is connected via
a first capacitor, and the second terminal of the AC input portion and the second output port of the secondary-side circuit
is connected via a second capacitor thereby preventing a direct current from flowing into the AC input portion.
