Pulse generator

Pulse generator

A pulse generator is a device that produces electrical pulses through the use of a signal generator, pulse generating electric circuits, and solid phase high speed switching devices. There are various types of pulse generators, including resistance-capacitance-type relaxation generators, rotary impulse-type generators, and electronic pulse generators.From: Food Processing Operations Modeling [2019], Advanced Manufacturing and Processing Technology [2020]

Pulse generation: For the electron beam micromachining (EBMM), pulsed DC power supply is required, and the pulse generator generates pulses as per requirement. Various types of pulse generators are resistance–capacitance-type (RC-type) relaxation generator, rotary impulse-type generator, electronic pulse generator, and so on.

The single ideal pulse signal from the pulse generator is shown in Figure 4. The waveform of the pulse signal is determined by the characteristics of the pulse generator (Emmerich et al., 2016). In this paper, the pulse generator is actually a rotary valve. Opening and closing the valve are the process of changing the channel flow area, which can produce positive pulse signals (Perry, Burgess, & Turner, 2008). Considering the low-power design of the downhole system and the characteristics of the pulse generator, opening and closing the valve create a series of momentary pressure changes, which includes rising and falling edges of the positive pulses. In accordance with this condition, the single ideal pulse signal from the pulse generator is a trapezoidal wave which has a width of 2 s.
