Radioisotope power systems (RPS), Advanced Modular Power Systems (AMPS) and Solar Electric Propulsion (SEP) are programs that will directly benefit from this development. Hall thruster PPUs voltage requirements include a 120V input for a 300V direct drive, a 300V input unit and a discharge module with a wide input voltage range of 300V-600V. Also, roll-out photovoltaic arrays are tailored to 120V and 300V for SEP applications. These are voltage ratings that are ideally suited to PML capacitors. One PML capacitor can replace multiple tantalum capacitors that are often used in parallel-series configuration.
Capacitors are used in most all electrical and electronic systems ranging from consumer electronics, to industrial electronics, medical instrumentation, transportation, communications and defense. DC-Link capacitors are needed to absorb ripple currents and transient voltage pulses created by switching devices such as IGBT, IGCT and MOSFETs used to convert lower DC voltage to higher DC and AC voltages. The proposed PML DC-link capacitors, have applications in inverter circuits used in renewable energy power generation systems, including photovoltaics and wind power generation, hybrid and electric vehicles and modular energy storage systems tied to the smart grid. PML capacitors are smaller, they have lower cost and higher performance, which will improve life and reliability of power converters. Hybrid and electric automotive drives will particularly benefit from the higher temperature and lower volume and weight of PML capacitors.
