Different wave generator circuit is used troubleshoot electronics circuit. In this circuit, a square wave is filtered by a high-order low-pass filter so that a -3-dB frequency will eliminate most harmonics of the waveform. The Sine Wave Generator is an excellent tool for generating waves with speakers or for our Mechanical Wave Driver. This IC reduces motor driving noise by using a high-efficiency, sine wave PWM drive type. Sine waves are produced by a resonant circuit when the voltage across the output rises and falls in a sinusoidal. The below given diagram shows a simple sine wave generator circuit which may be used for driving the above inverter circuit, however since the output from this generator is exponential by nature, might cause a lot of heating of the mosfets. Kisae Sine Wave Power Inverter and Charger — 2,000 Surge Watts, 1,000 Rated Watts, 40 Amp Multi-Stage Charger, Model# IC121040. A better wave for audio purposes is the sine wave.
