The proposed technique is conceived to be used in inverters featuring one ... and compared to that of other conventional pulse width modulation (PWM) techniques. The scientists assumed a switching ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM ... experiment with pulse density modulation. The idea is to use smaller pulses over a longer ...

[Chris] did and asserts that he doesn’t care because he can just use the PDM system to get the same result. PDM — pulse density modulation — is similar to PWM and, like PWM, requires a ...

The proposed new approach, which the researchers claim can be applied without additional equipment, combines virtual impedance and a modified pulse-width modulation strategy to suppress fault ...

Inside the latest 16-phase power controller from Alpha and Omega Semiconductor and how it helps feed power-hungry GPUs and ...
