This power supply is a switching
power supply . Its output power is 300w. It uses a half-bridge power
converter because it has low reverse voltage requirements for the power switch tube,
transistors are easy to select, and the price is cheap. The voltage
at both ends is positive and negative symmetrical, and the magnetic flux of the transformer changes from +
to +. The transformer utilization rate is high, so the volume is small; it also
has anti-unbalance ability.
The control circuit first uses the domestic integrated spider X2527 pulse width modulator
, which makes its power supply circuit relatively simple, uses fewer components, is easy
to make , and has high reliability.
Compared with the series linear power supply, the switching power supply has the advantages of high efficiency, small size, and light weight.
