Abstract:
In recent, high frequency power converters are
more popular due to extensive use in electric vehicle and micro
grid applications. In high frequency power converters PCB
designing is an important part of the circuit designing specially
for high-frequency operation. In all power electronics systems,
PCB is used for compact circuits but the effect of parasitic
elements in the PCB is usually neglected. While designing the
gate driver circuit for high-frequency operation devices
requires proper characterization of the PCB parasitic element
along with the other resistive and capacitive elements used.
Even in lower frequencies if the parasitic elements not
considered creates ripples in the output. The paper presents a
detailed pole-zero analysis of a simple gate driver circuit and
the effect of different frequency operations on the same design
to represent the need for different values of external resistor
and capacitor to get the best voltage waveform to feed the gate
terminal of the power device.
