The relationship between each system and security will become increasingly important. The question now is: Are there any systems that are insecure?Automotive safety has improved in recent years, both
In a single-phase full-bridge inverter circuit, in order to output a sinusoidal AC waveform, the signal given to the switch tube is an SPWM wave. If a PWM wave is given to the switch tube, and then an
