。Applying a DC input voltage to one end of an active element having a control electrode,
In a DC-DC converter that intermittently supplies DC at the other end of the active element to the primary side of the transformer and rectifies and smoothes the output on the secondary side of the transformer to obtain a DC output, from the transformer to the active element. A DC output higher than the voltage on the transformer side is obtained from a rectifying and smoothing circuit, the output of the smoothing circuit is applied to the power supply terminal of the error amplifier, and the DC representing the voltage obtained at the transformer is input to the error amplifier to obtain the reference value. get the error of
A constant voltage power supply circuit in which the error signal controls the active element to control the voltage obtained at the transformer to a constant value.
