Capacitance Conversion Calculator
This converter consists of a single-phase diode rectifier, a small film capacitor at the DC-link, a voltage source three-phase inverter, and an interior permanent magnet (IPM) synchronous motor. In this system, the inverter regulates both the velocity of the IPM motor and the input-current waveform.
The ESR of each capacitor is about 1ohm so with 3.5A rms, each will be dissipating about 10W. If we look at film capacitors, again from the TDK B32678 series, just four in parallel totaling 160µF, 450V give 132A rms capability with a …
