A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the design and purpose of the inverter. Examples include: • 12 V DC, for smaller consumer and commercial inverters that typically run fro. Hundreds of thousands of volts, where the inverter is part of a high-voltage direct current power transmission system. An inverter may produce a square wave, sine wave, modified sine wave, pulsed sine wave, or near-sine pulse-width modulated wave (PWM). . The instantaneous values of a sinusoidal waveform is given as the “Instantaneous value = Maximum value x sin θ ” and this is generalized by the formula. Where, Vmax is the maximum voltage induced in the coil and θ = ωt, is the rotational angle of the coil with respect to time. If we know the. . Each 555 is running as a high frequency oscillator, usually in the range of few kHz to many kHz. The sine wave from the RC integrator is fed into pin 5 of the 555, which is the control voltage pin.
