Abstract—This paper first introduces the principles and
features of constant voltage transformer and current-controlled
voltage stabilizing circuits, both of pose the constant
voltage transformer DC power supply put forward later with
high performance and efficiency. Finally, the paper illustrates the
circuit of power supply that can put into practice.
Index Terms—regulator transformer, CVT, power supply,
high efficiency
I. INTRODUCTION
In general, constant voltage DC power supply divided into
switching stabilized voltage supply,voltage-controlled voltage
supply and current-controlled voltage supply. The features of
switching stabilized voltage supply include high efficiency
power supply and wide stabilized range, but the ripple and the

interference signal are considerable, and the cost of product is
also expensive. Furthermore, the stabilized performance has Structurally, the constant voltage transformer is made up of a
no advantage. The stabilized performance of voltage- simple transformer, a core of secondary ic circuit and a
controlled voltage supp
