DC step-up is to upgrade the lower DC battery voltage to a required voltage. The basic work process is shown in the following: firstly the low-voltage pulse is throughhigh-frequency oscillation; then a predetermined voltage value is stepped-up by a pulse transformer; afterwards, high-voltage direct current is obtained by pulse rectifier. Thus, DC boost circuit is classified into DC / DC circuits. In the portable battery-powered devices, the high voltage required in the circuit is usually obtained by DC boost circuits. These devices include cell phones, pagers, other wireless communications equipment, camera flash, portable video display device and power equipment such as electric shock and so forth.
