    • A power supply (1) for a pulsed load (2) includes a first energy storage device in the form of a battery (3) which is in parallel with a second energy storage device in the form of a supercapacitor (4) Battery (3) and supercapacitor (4) are respectively modelled as: an ideal battery (7) in series with an internal resistance (8); and an ideal capacitor (9) in series with an equivalent series resistance (ESR) (10). Through use of a supercapacitor (4) having a low ESR with respect to the resistance (8), the power supply (1) facilitates continuity of supply to load (2). That is, during peak demand more of the load current will be supplied by supercapacitor (4) due to the lower ESR. Moreover, during times of lower load current demands the battery recharges the supercapacitor. This reduces the peak current needed to be provided by the battery and thereby improves battery longevity.
    • 用于脉冲负载(2)的电源(1)包括电池(3)形式的第一能量存储装置,其与超级电容器形式的第二能量存储装置并联(4)电池(3) )和超级电容器(4)分别建模为:与内阻(8)串联的理想电池(7); 以及与等效串联电阻(ESR)(10)串联的理想电容器(9)。 通过使用相对于电阻(8)具有低ESR的超级电容器(4),电源(1)有助于连续供给负载(2)。 也就是说,在峰值需求期间,由于较低的ESR,更多的负载电流将由超级电容器(4)提供。 此外,在较低负载电流要求的时期,电池为超级电容器充电。 这降低了由电池需要提供的峰值电流,从而提高了电池寿命。
