Q1: What are the operating modes and output voltage modes of a switching power supply?

A switching power supply features three operating modes for control: fixed frequency with fixed pulse width modulation, adjustable frequency and adjustable pulse width, and fixed frequency with adjustable pulse width. The fixed frequency and fixed pulse width mode is typically applied in DC/AC inversion or DC/DC voltage conversion, while the other two modes are used in switching voltage regulators. It also offers three voltage output modes: direct output, average output, and amplitude output, where direct output suits DC/AC inversion or DC/DC conversion, and average and amplitude outputs serve switching voltage regulator applications.

Q2: How are switching power supplies classified by circuit connection and structure?

Switching power supplies can be divided into series, parallel, and transformer types based on their circuit connection methods. Transformer-type switching power supplies are further categorized into push-pull, half-bridge, and full-bridge types; according to transformer excitation and voltage output phases, they can also be classified as forward, flyback, single-ended, and double-ended types, with additional classifications available based on specific application purposes.
