- Long delay timer sans large capacitorsThere are several applications at home or industry for long delay timers (ON or OFF delay). Time delays on the order of seconds can be generated using 555 timer circuits, provided the timing capacitor values do not exceed the limit specified by 555 datasheets. When the time...26-09-2024
- Single phase mains cycle skipping controller sans harmonicsIn electrical heating applications, resistive heaters are powered through phase angle-controlled SCR/triac circuits to vary the applied voltage/power to maintain the required temperature. Phase angle control produces a lot of harmonics leading to power line...15-04-2024
- A long pulse detector circuitThere are several applications in which pulses longer than the set width are to be detected, ignoring the other short pulses. We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train where the pulses are of equal...17-10-2023
