Moreover, modern film capacitors not only perform better but can be a cost effective technology as well if applied correctly. inductance in an inverter power bridge leads to inefficiencies due to the voltage spikes they produce when the power devices are switched on and off at a high rate of dI/dt.
So beyond a certain point, adding capacitance does little to enhance the performance of the inverter. = 308 uF That’s 16 times less capacitance than that of the electrolytic capacitor! Certainly packaging a 308 uF capacitor verses a 5,000uF capacitor makes for a smaller, lighter and more compact design.
The first step in sizing capacitors for inverter bus link applications should be to understand how much bus link capacitance is required for a given inverter design. The biggest design limitation for electrolytic capacitors in inverter applications has been the amount of ripple current that the electrolytic capacitor can sustain.
Electrolytic capacitors have been the workhorse technology for hard switched inverter bus link capacitors for many years. Electrolytic capacitor technology has also remained virtually unchanged over the years. Up till now, the greatest benefit in using electrolytic capacitors for bus link capacitors in inverters has been their cost.
Most inverter designs with large amounts of capacitance add circuitry to discharge the bus link capacitors in a quick and safe manner upon power down so as not to present a safety concern. This of course adds complexity and cost to an inverter’s overall design. Film capacitors do cost more per uF than electrolytic capacitors.
II. THE BUS LINK CAPACITOR’S ROLE The bus link capacitor is used in DC to AC inverters to decouple the effects of the inductance from the DC voltage source to the power bridge. Figures 1A and 1B show two examples of a typical hard switched pulse width modulated (PWM) inverter that converts DC voltage to a three phase AC voltage.
