ABSTRACT:
A high power factor, regulated synchronous converter for converting 110-volt, rectified, 50-60 Hz alternating current into a direct current output, which has enhanced hold up (energy storage). The circuit includes a half-bridge inverter for converting the half-wave rectified voltage into high frequency alternating current in the range of 20-30 KHz. The high frequency alternating current is coupled through an inductance coil to a half-bridge synchronous regulator/rectifier which produces a direct current output. The energy delivered to the half-bridge synchronous regulator/rectifier is stored in a capacitor, and the voltage across the capacitor may be regulated making energy storage independent of the line voltage. Additional synchronous regulator/rectifiers may be coupled to the circuit to produce additional direct current outputs.
