Switching power supply 30V supplier tells you that switching power supply is to use electronic switching devices (such as transistors, field effect transistors, thyristors, etc.) to make electronic switching devices "on" and "off" continuously through the control circuit "off", let the electronic switching device perform pulse modulation on the input voltage, so as to realize DC/AC, DC/DC voltage conversion, as well as adjustable and automatic voltage regulation of the output voltage.

Switching power supplies generally have three working modes: fixed frequency and pulse width mode, fixed frequency and variable pulse width mode, and variable frequency and pulse width mode. The supplier of Switching power supply 30V tells you that the former working mode is mostly used for DC/AC inverter power supply, or DC/DC voltage conversion; the latter two working modes are mostly used for switching regulated power supply. In addition, the switching power supply output voltage also has three working modes: direct output voltage mode, average output voltage mode, and amplitude output voltage mode. Similarly, the former working mode is mostly used for DC/AC inverter power supply, or DC/DC voltage conversion; the latter two working modes are mostly used for switching regulated power supply.
Switching power supply 30V supplier tells you that according to the way switching devices are connected in the circuit, switching power supplies can be roughly divided into three categories: series switching power supply, parallel switching power supply, and transformer switching power supply. Among them, transformer-type switching power supply (referred to as transformer switching power supply hereafter) can be further divided into: push-pull type, half-bridge type, full-bridge type, etc.; according to the excitation of the transformer and the phase of the output voltage, it can be further divided into: forward type , flyback, single-excited and double-excited, etc.; Switching power supply 30V suppliers tell you that if you divide it from the purpose, it can be divided into more types.
