Patent
Delta Electronics Inc | Date: 2017-05-03

A power conversion device includes a casing, a middle plate and a converter module. The casing includes a base plate. The base plate has a concave recess therein. The base plate forms a base plate convex hull at a side opposite to the concave recess. The middle plate has a middle plate groove therein. The middle plate groove corresponds to the base plate convex hull. The middle plate and the base plate combine up, such that the base plate convex hull fluidly seals the middle plate groove, making the middle plate groove to form a first coolant channel. The converter module is at least partially located in the concave recess.

A method for controlling modulation wave and a three-phase three-wire three-level circuit are provided. The method for controlling modulation wave is applied in the three-phase three-wire three-level circuit. Three bridge arms of the three-phase three-wire three-level circuit correspond to three modulation waves. The three-phase three-wire three-level circuit is controlled by comparing said three modulation waves and a carrier wave. The method for controlling modulation wave includes: obtaining a primary modulation wave from said modulation waves based on currents corresponding to each phase of the three-phase three-wire three-level circuit; and adding a shifting quantity to said three modulation waves such that the primary modulation wave is shifted to a peak value, a valley value, or a middle value between the peak value and the valley value of the carrier wave.


A single phase brushless DC motor comprises a Hall effect sensor, a coil assembly and a motor control circuit which generating a driving signal to guide a coil current flowing through the coil assembly. The Hall effect sensor senses the magnetic pole of the rotor to accordingly generate a Hall effect signal. The motor control circuit outputs a current polarity reverse signal according to the voltage at one end of the coil assembly. The time when the current polarity reverse signal is generated corresponds to the polarity reverse time of the coil current. The motor control circuit adjusts the phase of the driving signal according to the polarity reverse time of the Hall effect signal and the time when the current polarity reverse signal is generated to synchronize the phase of the back emf of the single phase brushless DC motor with the phase of the coil current.
