Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular ("flat-topped"), rather than sinusoidal, pulses. [1] Pulsed DC is commonly produced from AC (alternating current) by a half-wave ...
See the circuit diagram on the right. At first, n capacitors (C) are charged in parallel to a voltage V C by a DC power supply through the resistors (R C). The spark gaps used as switches have the voltage V C across them, but the gaps have a breakdown voltage greater than V C, so they all behave as open circuits while the capacitors charge. The ...
A pulse-forming network for an Nd:YAG laser rangefinder The Shiva Star device at Air Force Research Laboratory, USA, which generates pulsed power for high-energy fusion power experiments. Each of the 6 radial arms is a pulse-forming line delivering a pulse of energy to the center, whose capacitors store a total of 10 MJ of energy and can create ...
In electronics, it is common to refer to a circuit that is powered by a DC voltage source such as a battery or the output of a DC power supply as a DC circuit even though what is meant is that the circuit is DC powered. In a DC circuit, a power source (e.g. a battery, capacitor, etc.) has a positive and negative terminal, and likewise, the load ...
Pulse generators may use digital techniques, analog techniques, or a combination of both techniques to form the output pulses. For example, the pulse repetition rate and duration may be digitally controlled but the pulse amplitude and rise and fall times may be determined by analog circuitry in the output stage of the pulse generator.
PWM rectifier (Pulse-width modulation rectifier) is an AC to DC power converter, that is implemented using forced commutated power electronic semiconductor switches. Conventional PWM converters are used for wind turbines that have a permanent-magnet alternator. [1] Today, insulated gate bipolar transistors are typical switching devices.
