Simple 400V DC Power Supply

Simple 400vdc power supply

This is a very simple 400V DC power supply circuit diagram, or, it may called as 230VAC to 400VDC converter. The working principle of this circuit diagram is very simple. You already knew the working principle of a bridge rectifier. This circuit is same as bridge rectifier and the working principle is also same. The fuse is used to protect the circuit, if the current is greater than 1 A.

Components List:

F1 = 1 A
B1 = IN4007
C1 = 470uF/450V
V1 = 230 V AC

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
