Investigation of Capacitors for Static Inverter Space Applications

Capacitor sinusoidal alternating current characteristics were obtained as a function of temperature and frequency. Calorimeter measurements of capacitor heat loss rates were used to determine dissipation factors and to correct impedance bridge data. Application of dissipation factor data to the rms component values of the commutating capacitor complex waveforms yielded excellent agreement with commutating capacitor losses as measured by calorimeter.
