General Information
USB: Universal Serial Bus; is a serial bus standard that allows devices to be connected using the "Plug and Play"
concept.
PE: Protective Earth.
RFI Filter: Radio-Frequency Interference Filter for interference reduction in the Radio-Frequency range.
PWM: Pulse Width Modulation; pulsed voltage at the input of the regenerative converter.
Switching Frequency: frequency of the IGBTs switching, normally expressed in kHz.
General Enable: when activated, the converter controls the voltage at the DC Link. When deactivated, this
function immediately blocks the PWM pulses. The General Enable function may be controlled through a digital
input set to this function.
Heatsink: metal device designed to dissipate the heat generated by the power semiconductors.
