Square-wave generator circuit
T1 and T2 in the circuit form the inherent oscillator, while T3 serves as the output stage. The network consists of a high-pass filter (C3, C4, R6, and R7) and a low-pass filter. The output from this network is fed...
400-Volt 60-watt push-pull power supply
The design provides a regulated output of 400 V and 60 W. The TL494 switching regulator controls the operating frequency and output voltage regulation. Resistor R1 and capacitor C1 set the switching frequency, which is approximately 0.5 to 100 kHz...
100khz square wave generator
The form of a musical signal never resembles a square wave. The frequency range perceived by an average adult rarely exceeds 17 kHz. Therefore, the appropriateness of testing audio amplifiers with a 100 kHz square wave signal is often debated....
Inverter Schematics
A small bias on the bases of Q1 and Q2 through R1 and R2 assists in initiating the circuit. This provides each transistor's base with a slight forward bias, enabling both transistors to conduct when the circuit is initially powered...
HV regulator with foldback current limiting
A TMOS MTM7N45 (Q2) is utilized as a series pass element in a linear high voltage supply that accepts +275 V unregulated and produces 250 V regulated with foldback current limiting. A 15 V zener diode (D1) provides the DC...
Simple Alarm Circuit
