Half-wave rectifier
The simplest scheme of half-wave rectifier consists of only one rectifying current element (diode). On the way out - a pulsating direct current. On the industrial frequency (50-60 Hz) is not widely used because the equipment required for power smoothing filters with high values of capacitance and inductance, which leads to an increase in weight, size and weight of the rectifier. However, the scheme is a half-wave rectification has found very widespread in the switching power supply with frequency AC voltage above 10 kHz, is widely used in modern household and industrial equipment. This is explained by the fact that at higher frequencies rectified voltage to obtain the required characteristics (specified or allowable rate fluctuations), are necessary elements of smoothing with smaller values of capacitance (inductance). Weight and size of power sources decreases with increasing frequency of the input AC voltage.
