For decades, Silicon-Controlled Rectifier (SCR) chargers dominated the utility industry, providing reliable, if somewhat bulky, power conversion. But as technology and customer expectations have evolved, switch-mode power supply (SMPS) chargers are quickly becoming the industry standard — and for good reason. In this article, we’ll explore why switch-mode chargers outperform traditional SCR technology, from efficiency […]

First of all, a definition Ripple is the AC component of a system’s charging voltage imposed on the DC bus. It can also be reflected from load equipment. It could be caused by poor charger design, poor inverter design, failing capacitors, or by the interaction of load equipment connected to the DC bus. The result […]
Although noise & ripple currents occur in many standby battery systems, there is a certain amount of controversy about their effects on lead-acid cells; some believing it has virtually no effect and some claiming it shortens the service life of the battery. It can be shown however that even where the ripple current is very […]
