Abstract
An auxiliary power circuit of a conversion module is used to supply power to a control unit, and an input end of the conversion module includes an even number of energy storage units coupled in series. The auxiliary power circuit includes an even number of primary-side circuits and a secondary-side circuit. Each primary-side circuit includes a first switch unit, a second switch unit, and a resonance tank. The first switch unit is connected to the second switch unit in series, and is correspondingly connected to one of the energy storage units in parallel. The resonance tank is connected to the second switch unit in parallel. The secondary-side circuit is coupled to the resonance tanks of two of the primary-side circuits to acquire power and supply power to the control unit.
