Study Notes
SCR Circuit Analysis
- The circuit consists of a resistor (R), a power source (V), and a Silicon-Controlled Rectifier (SCR) triggered at 25°.
- The maximum voltage connected to the SCR circuit is 120-V.
- The goal is to determine the DC voltage delivered to the load, which is the resistor (R).
- The triggering angle of the SCR is 25°, which affects the DC voltage output.
SCR Circuit Analysis
- In an SCR circuit, when the maximum voltage of 120-V is connected and the SCR is triggered at 25°, the DC voltage delivered to the load is approximately 36.4 V.
SCR Characteristics
- An SCR has 4 layers and 3 terminals.
- Note: This is a key characteristic of an SCR device.
