Рис. ABBThe AC mains voltage (50/60 Hz) applied at the input side is transformed to a lower level and rectifi ed by a subsequent rectifi er. Then, a capacitor C smoothes the output voltage of the rectifi er. The dimension of the transformer depends on the desired output voltage.
Due to the design of the electric circuit, the output voltage directly depends on the input voltage which in turn means that variations of the mains voltage have direct effect to the output side. Since no regulation is done on the secondary side, the residual ripple of the output voltage is in the dimension of volts and specifi ed as a percentage of the DC output voltage.
Due to their simple design, unregulated power supplies are very robust and durable. Their effi ciency is approx. 80 %.
Unregulated power supplies are primarily used for simple electromechanical applications that do not require exact output voltages, e.g. for the supply of contactors.

Рис. ABBThe AC mains voltage is transformed to a lower level, rectified and smoothed by capacitor C1. Then, voltage regulation is performed, typically using a power transistor. The power transistor acts as a variable resistor, controlled to keep the output voltage constant.
The efficiency of linearly regulated power supplies is only approx. 50 % due to the high losses inside the power transistor. The remaining energy is emitted in the form of heat. Due to this, sufficient ventilation is required to cool the power supply. Compared with unregulated power supplies, linearly regulated power supplies have a very small residual ripple of the output voltage (in the dimension of millivolts).
Linearly regulated power supplies are used for all applications that require a very exact output voltage, e.g. for highly precise medical devices.
