The first chargers were linear power supplies but they quickly moved to the cost effective ringing choke converter (RCC) SMPS topology, when new levels of efficiency were required. SMPS. The only heat generated is in the non-ideal aspects of the components and quiescent current in the control circuitry. regulations. Power factor Low for a regulated supply because current is drawn from the mains at the peaks of the voltage sinusoid, unless a choke-input or resistor-input circuit follows the rectifier (now rare). Switching supplies in computers, TVs and VCRs have these opto-couplers to tightly control the output voltage. PFC guide.

certain period of time. Failure of the switching transistor is common. Ideal switching elements (e.g., transistors operated outside of their active mode) have no resistance when "closed" and carry no current when "open", and so the converters can theoretically operate with 100% efficiency (i.e., all input power is delivered to the load; no power is wasted as dissipated heat). selection.

Switching losses in the transistors (especially in the short part of each cycle when the device is partially on), on-resistance of the switching transistors, equivalent series resistance in the inductor and capacitors, and core losses in the inductor, and rectifier voltage drop contribute to a typical efficiency of 6070%. Due to their high volumes mobile phone chargers have always been particularly cost sensitive. Failure modes[edit].
