摘要： The present invention relates to a reference current circuit. The reference circuit comprises a low-level current bias circuit, a voltage proportional-to-absolute temperature generator for creating a proportional-to-absolute temperature voltage (VPTAT), and a MOSFET-based constant-IC regulator circuit. The MOSFET-based constant-IC regulator circuit includes a constant-IC input and constant-IC output. The constant-IC input is electrically connected with the VPTAT generator such that the voltage proportional-to-absolute temperature is the input into the constant-IC regulator circuit. Thus the constant-IC output maintains the constant-IC ratio across any temperature range.

摘要： A three-phase alternating current (AC) to direct current (DC) converter may include a three-phase AC filter receiving a three-phase AC power supply, a plurality of three-phase current source rectifiers (CSR) connected in parallel with each other and connected to a three-phase AC filter, and an output filter connected to the CSR's to generate a DC output. Each of the CSRs may include six switches and a free-wheeling diode. Each of the three filtered AC inputs from the three-phase AC filter may be connected via a switch of the six switches to selectably send current into a positive line, and each of three filtered AC inputs from the three-phase AC filter may be connected via another switch of the six switches to selectably receive current from a negative line. The free-wheeling diode may have a cathode connected to the positive line and an anode connected to the negative line.
