According to textbooks, a sine wave is a wave whose form resembles a sine curve. Often in power electronics, we need a sine wave generator for some applications; a dc/ac power inverter, for example.

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables ...

What is a high frequency generator circuit? High frequency waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can ...

Toshiba’s new 600 sine-wave PWM driver IC targets the three-phase brushless motors widely used in home appliances and industrial equipment.

The circuit is a simple transimpedance amplifier that converts the device under test’s (DUT’s) IDS into an output voltage (Fig. 1). O p-amp U1A maintains the DUT’s source voltage at 0 V.

Toshiba’s Hall sensorless sine-wave drive three-phase brushless DC motor control pre-driver IC helps reduce vibration and noise of high-speed motors.

Even with a sine and triangle generator, the circuit could be used to add safety limits to the output voltage (even a simple diamond buffer would be an improvement over some of the ham-fisted ...

Toshiba Electronics Europe has launched a three-phase brushless DC (BLDC) motor control pre-driver IC for motors that require high rotation speeds. Suitable for server fans, pumps, blowers and suction ...

I have just discovered that Apex Microtechnology of Arizona actually makes a chip, the SWR200 Precision Sine Wave Reference, to do much the same thing, a nice low-distortion sine wave with a ...

KAWASAKI, Japan —TC78B011FTG adopts a sine-wave drive method that does not use Hall sensor control. This helps to reduce vibration and noise. In addition, a built-in closed loop speed control function ...
