摘要： A planar transformer (2A) is configured on a multi-layer circuit board (CB 1) of a resonant converter (100). The planar transformer (2A) includes multiple layers of primary-side traces (Tp1), multiple layers of secondary-side traces (Ts1), and an iron core (C1). The primary-side traces (Tp1) serve as a primary-side coil (22A) of the transformer to generate a first direction magnetic flux (F_D1) when the resonant converter (100) operates. The secondary-side traces (Ts1) serve as a secondary-side coil (24A) of the transformer to generate a second direction magnetic flux (F_D2) when the resonant converter (100) operates. The primary-side traces (Tp1) and the secondary-side traces (Ts1) surround a first core pillar (C12) and the second core pillar (C14), and the primary-side traces (Tp1) and the secondary-side traces (Ts1) are configured in a specific stacked structure on the multi-layer circuit board (CB1), so that a magnetomotive force (MMF) of the planar transformer (2A) can maintain balance during the operation of the resonant converter (100).

摘要： A novel phase-shift based modulation strategy is disclosed that enables a DC-DC converter (100) to operate with zero-voltage-switching (ZVS) across wide voltage and power range. The converter (100) operates at a fixed fundamental frequency, with the output current controlled based on an amount of phase shift of the fundamental component at the output of an inverter portion (110) of the converter (100). To achieve soft switching, a rectifier portion (130) of the converter (100) is controlled to phase shift the fundamental component of the rectifier voltage observed at a rectifier reference terminal (131). More specifically, by requiring a phase shift of the voltage at the rectifier reference terminal (131) relative to the output voltage of the inverter (110), the inverter current is such that ZVS is achieved. A converter (100) and method are provided to implement DC-DC conversion with soft switching.

摘要： An insulation resistance detection circuit is coupled to a positive end (V+) and a negative end (V-) of a DC power source (Vdc), and is used to detect a positive insulation resistance (Rx) between the positive end (V+) and a ground point (G) and detect a negative insulation resistance (Ry) between the negative end (V-) and the ground point (G). A detection unit (DET) sets a first estimated resistance and a second estimated resistance, and acquires a first voltage (V1) based on turning on the switch (SW) and acquires a second voltage (V2) based on turning off the switch (SW). The detection unit (DET) calculates a third voltage (V3) and a fourth voltage (V4) according to the first estimated resistance and the second estimated resistance so as to detect the positive insulation resistance (Rx) and the negative insulation resistance (Ry) when the third voltage (V3) is equal to the first voltage (V1) and the fourth voltage (V4) is equal to the second voltage (V2).

摘要： A method of clamping an output current of a three-phase power converter is provided. The three-phase power converter includes three switch bridge arms and provides a three-phase output voltage command (V ref_max , V ref_mid , V ref_min ), and each switch bridge arm has an upper switch (S u1 , S v1 , S w1 ) and a lower switch (S u2 , S v2 , S w2 ) connected in series. The method includes steps of: determining that the output current (i u , i v , i w ) is greater than a first current threshold value to activate a current clamping control procedure, comparing a carrier signal with the three-phase output voltage command (V ref_max , V ref_mid , V ref_min ) to turn on the lower switches (S u2 , S v2 , S w2 ) by a first zero vector (vo) when the carrier signal is rising and turn on the upper switches (S u1 , S v1 , S w1 ) by a second zero vector (v 7 ) when the carrier signal is falling, determining that the output current (i u , i v , i w ) is greater than a second current threshold value to activate an overcurrent protection procedure, wherein the second current threshold value is greater than the first current threshold value.
