First and circuit board assemblies comprising respective booster and DC/DC converter circuits are mounted to the heatsinking structure such that at least portions of the circuit board assemblies lie in the channel. First and second end caps are attached to the heatsinking structure at respective first and second ends of the channel. Environmental seals may be provided at the first and second ends of the channel. The booster circuit may be operative to produce a first DC voltage and the DC/DC converter circuit may be operative to produce a second DC voltage from the first DC voltage such that the second DC voltage is at least about ten times less than the first DC voltage.

摘要： A boost converter topology is disclosed that includes a resonant network comprising a snubber inductive element having a primary winding connected in series to a first resonant diode that is connected, at a first node, to two series connected additional resonant diodes and a secondary winding coupled to a fourth resonant diode connected to the first node. The present invention has the advantage of reducing the energy stored in the parasitic capacitor of the first resonant diode by a factor of four at the turn off of the main control switch. This reduction is achieved by allowing only a small amount of energy transfer to the snubber inductive element so that it does not turn the two additional resonant diodes on before the auxiliary switch is turned on, thus reducing losses and EMI associated with turning on the auxiliary switch.

摘要： An AC-DC converter is provided which comprises a booster circuit 9 which has a MOS-FET 6 and a reactor 4 connected in series to MOS-FET 6 for generating a DC output voltage VOUT; a voltage generator 11 for providing a reference voltage VR; and a control circuit 10 for comparing reference voltage VR and DC output voltage VOUT and generating outputs to turn MOS-FET 6 ON and OFF in response to the difference between reference voltage VR and DC output voltage VOUT. The control circuit 10 comprises a voltage detector 18 for measuring an input voltage VIN applied on an input terminal of the reactor 4; and a voltage retainer 22 for keeping output voltage VOUT on a level elevated by a substantially constant voltage VP+VR or VZ above input voltage VIN measured by voltage detector 18 such that booster circuit 9 simply raises input voltage VIN, even if on a lower level, by a substantially constant voltage with a smaller step-up ratio VOUT/VIN than that of a case for voltage increase up to a constant high DC output voltage regardless of a level of input voltage VIN.

摘要： A switching power source having a digital control system is provided. The switching power source includes a switching circuit 40 for switching an input power, an output circuit 50 for converting the switching output into a DC output, and a digital control 70. The digital control 70 is adapted to receive an output voltage analog signal AS1 and an output current analog signal AS2, and to convert the signals AS1 and AS2 into digital signals. It further functions to calculate, based on the digital signals, a command value for determining at least one of the switching frequency and the on or off time of the main switch 42. The operation of the main switch 42 is controlled in accordance with the command value. Information on power source input voltage or load terminal voltage is obtained through an assumption based on the signals AS1 and AS2.
