Title:
DC/DC CONVERTER CONTROL METHOD AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/142318
Kind Code:
A1
Abstract:
Provided is a DC/DC converter control device 50 capable of covering, with low loss, a wide range of power that can be output. The control device 50 has a selection control unit 60 and a comparison control unit 70. The selection control unit 60 has a reference signal generation unit 61, a minimum value selection unit 62, and a voltage control unit 63. The comparison control unit 70 has a comparison unit 71, a frequency control unit 72, an inter-phase control unit, and a pulse drive unit 74. When charging a battery rapidly, for example, a DC output current Io is supplied to the battery by the frequency-control of the frequency control unit 72. In a power supply region under a boundary line BL of a current resonance control limit in which control is difficult, the frequency control is switched to the inter-phase control of the inter-phase control unit 73 and the DC output current Io is supplied to the battery.
