27 lut 2024 · Silicon Controlled Rectifier is a four-layer current-controlling device, which is used in devices like dimmers. These are used in device that require the control of high power and high voltage. The working of the whole region of the SCR circuit predominantly relies upon the method of its triggering.
25 paź 2024 · Q2. Write a Python function to reverse a string. Sample Answer: This function, named reverse_string, takes a single string as input and uses Python’s slicing feature to return the string in reverse order. Slicing allows for concise manipulation of strings, making it easy to reverse them with just one line of code.
30 paź 2024 · Question 2: Explain Python’s key features. Python's features are well-suited for data engineering: Easy-to-Read Syntax: Python’s syntax is simple and resembles natural language, which is beneficial for collaboration or debugging. Dynamic Typing: Python is dynamically typed, so types are inferred at runtime.
15 wrz 2023 · Thyristor or SCR (Silicon Controlled Rectifier) Viva Interview Questions and Answers. Question 1: What is an SCR? Answer: An SCR, or silicon-controlled rectifier, is a four-layer semiconductor device that can be used as a switch. It has three terminals: anode, cathode, and gate.
This set of Power Electronics Multiple Choice Questions & Answers (MCQs) focuses on “Firing Circuits-1”. 1. In a single pulse semi-converter using two SCRs, the triggering circuit must produce. a) two firing pulses in each half cycle. b) one firing pulse in each half cycle.
Triggering/Firing. This method of securing SCR conduction is called triggering or firing, and it is by far the most common way that SCRs are latched in actual practice.
