Abstract: An SMPS received a rectified periodic input line voltage and is configure to provide a regulated output. A power switch has a constant turn-on time in a given cycle of the rectified periodic input line voltage. A maximum value of the envelope of peak currents through the power switch is determined and is compared with a reference value, and the power switch turn-on time in the next cycle is adjusted accordingly. The output of the power supply is regulated to a target output value, and the current is in phase with the periodic input line voltage, resulting in a high power factor. No sampling of the line voltage is needed to maintain the high power factor. A controller chip can have as few as five pins. Alternatively, a seven-pin controller chip can have two external resistors for selecting operations in either Boundary Conduction Mode (BCM) or Discontinuous Conduction Mode (DCM).

Abstract: This invention provides a gas wave pressure regulation method and apparatus, gaseous wave pressure regulator (GWPR), associated with a pressure energy recovery system which can be used in the processes of petrochemical and liquid natural gas (LNG) industries to recover the lost energy in a regulating process where a pressure regulation is needed to reduce the pressure level fitting the operating conditions, but the spontaneous temperature is undesirable. The said method and apparatus employ a mechanism creating a unsteady periodic flow by means of gaseous wave resonant interactions to convert the energy between the pressure drop into the form of heat without using any moving parts. The said heat is reused inside the GWPR to eliminate or diminish the temperature drop associated with the pressure regulation. The said pressure energy recovery system comprises a primary GWPR followed by a primary heat exchanger, and a secondary GWPR linked by a secondary heat exchanger operated in series.
