This is a three-phase motor H-bridge drive circuit.In the filter circuit composed of D1 and C1 in the figure, why is there a resistor R1 in parallel? My analysis is that it is intended to form a volta
The following figure shows the cross section of the sturdy coating film of Borus seen under a microscope. The cross section of the coating film of the copper series coating. The cross section of the c
In many electronic systems, a sine wave signal with adjustable frequency and amplitude is often needed as a reference or carrier signal. Sine wave signals are mainly generated by analog circuits or DD
Recently, Freescale Technologies of the United States demonstrated an example of using acceleration sensors to control car taillights. Even if the driver does not step on the brakes, the brake lights
