Document Type and Number:
WIPO Patent Application WO/2019/206229
Kind Code:
A1
Abstract:
Disclosed are a DCDC converter, a vehicle-mounted charger and an electric vehicle. The DCDC converter comprises a first adjustment module, a resonance module, a second adjustment module, and a controller. The first adjustment module is used to adjust a frequency of an input signal of the DCDC converter when a charge operation is performed, and to rectify an output signal of the resonance module when a discharge operation is performed. The resonance module is used to perform resonance processing on an output signal of the first adjustment module when the charge operation is performed, and to perform resonance processing on an output signal of the second adjustment module when the discharge operation is performed. The second adjustment module is used to adjust a frequency of an output signal of a battery module when the discharge operation is performed, and to rectify an output signal of the resonance module when the DCDC converter charges the battery module. The controller is used to control the first adjustment module and the second adjustment module according to a charge/discharge signal of the battery module so as to cause the battery module to perform a charge/discharge operation. The invention is provided with a resonance module, and thus is applicable to products with large power requirements.
