This is a control rechargeable delay circuit. Under normal circumstances, when there is no input signal, the transistor VTi is off. VTz is conducting, resulting in a low output potential (U). When a signal is applied, VTi turns on, VTz turns off, and the output (Us) becomes high potential. When the signal disappears, VTi turns off, VTz conducts again, and the output reverts to low potential. The signal appears at U, which goes high for the duration of the delay circuit. The time interval can be calculated using the formula: t = RC ln(Vs/V), where Vs is the regulator voltage, and V is the voltage between N and M. When UMW/E is -0.37, the time constant t = RC becomes more stable.
The control rechargeable delay circuit operates effectively by utilizing two transistors, VTi and VTz, to manage the signal input and output states. In the absence of an input signal, VTi remains in the off state, allowing VTz to conduct. This configuration ensures that the output voltage (U) is maintained at a low level, effectively grounding the output.
Upon receiving an input signal, VTi switches to the on state, which simultaneously turns off VTz. This transition causes the output voltage (Us) to rise to a high potential, indicating the presence of the input signal. The circuit's behavior is governed by the timing characteristics defined by the RC time constant, which is influenced by the resistive (R) and capacitive (C) components within the circuit.
The delay period during which the output remains high after the input signal is removed is determined by the equation t = RC ln(Vs/V). This relationship illustrates how the time delay is affected by the ratio of the regulator voltage (Vs) to the voltage across the components (V). The stability of the time characteristics is enhanced when the condition UMW/E = -0.37 is met, leading to a more predictable and reliable output response.
In practical applications, this delay circuit can be employed in various electronic systems where timed responses to input signals are critical. Its design allows for flexibility in adjusting the timing characteristics through the selection of appropriate resistor and capacitor values, enabling it to meet specific operational requirements in control systems, timers, and other electronic devices.As of control rechargeable delay circuit Under normal circumstances, when there is no input signal, the transistor VTi off.
