Pulsed DC, or pulsed direct current (PDC), combines attributes of both alternating current (AC) and direct current (DC). It is typically generated from AC using a half-wave or full-wave rectifier. Pulsed DC exhibits some characteristics of both AC and DC waveforms, as the voltage of DC remains roughly constant while the voltage of AC continuously varies between positive and negative values.
Applications of Pulsed DC
Pulsed DC has a broad range of applications in multiple industries, including reducing electric arcs when producing thin carbon films and increasing yield in semiconductor fabrication by lessening electrostatic build-up. Pulsed DC is also frequently utilized to power light-emitting diodes (LEDs) and decrease their brightness. Thus, this use of pulsed DC current has proven very valuable to the manufacturing and electronics industries. The thin film materials produced through this method are used in various electronic components.
Smoothing Pulsed DC
Pulsed DC current has diverse industrial applications, such as reducing electric arcs in thin carbon film production and enhancing semiconductor fabrication yield by mitigating electrostatic build-up. Moreover, it is commonly employed to power light-emitting diodes (LEDs) and reduce their luminance intensity. As a result, pulsed DC represents a crucial tool for the manufacturing and electronics sectors. The thin film materials produced by this procedure are utilized in multiple electronic devices.
