There are generally three modes of switching power supply: fixed frequency and pulse width mode, fixed frequency and variable pulse width mode, and variable frequency and pulse width mode. The former mode is mostly used in DC/AC inverters or DC/DC voltage conversion, while the latter two modes are mostly used in switching regulated power supply. In addition, the output voltage of switching power supply also has three working modes: direct output voltage mode, average output voltage mode and amplitude output voltage mode. Similarly, the former is mostly used in DC/AC inverters or DC/DC voltage converters; the latter two are mostly used in switching regulated power supply.
