The main advantage for SMPS is that it gives DC supplies that can deliver more power for a given size, cost and weight of the adapter. These are considerably more complex than linear regulated power supplies and have clear advantages. In modern use the most common adapter is the Switched Mode Power Supply (SMPS). However, some ripples from the AC voltage remain (See Figure 4). Essentially it releases stored energy when no voltage is being output from the rectifier. ![]() At its simplest, a circuit component known as a reservoir capacitor or smoothing capacitor is placed at the output of the rectifier. A smoothing circuit or capacitor is used to achieve this. However, a constant voltage is required for most devices that operate on direct current. ![]() Note the ripples in the output voltage.Īs seen in Figures 2 and 3, the output voltage of the two rectifiers still varies greatly. The output voltage (green) of a half-wave rectifier and smoothing capacitor from the input AC voltage (yellow). Due to half of the current being blocked, much of the supplied energy is lost, and the mean voltage of half-wave rectified power is lower than that of full-wave rectified power.įigure 4. The half-wave rectifier effectively blocks current flow in one direction through the use of a diode (see figure 2). There are two separate types of rectifiers: the half-wave rectifier and the full-wave rectifier. ![]() A rectifier then converts alternating current into direct current. The transformer initially converts a relatively high- voltage alternating current that is supplied by an electrical outlet to a lower voltage suitable for the device being powered. See Standby power for more detailed information.Ī simple AC adapter consists of a transformer, a rectifier, and an electronic filter. Older AC adapters waste quite a bit of electricity in the form of standby power, but recent regulations and subsequent innovations have reduced the amount of electricity wasted considerably. Direct current is also required to recharge batteries, making AC adapters essential for electronic devices like laptops (see Figure 1) and cell phones. An AC adapter used for charging a laptop battery.ĪC adapters convert a higher-voltage alternating current to a lower-voltage direct current for use with devices that require a relatively constant voltage (within a tolerance).
