Control Method and Control Apparatus |
摘要 |
A control method and a control apparatus are provided. The control method and apparatus are applied to a BUCK-BOOST topology. The method specifically is, processing an output signal of a topology to obtain a pulse width modulation signal, performing an OR operation between the pulse width modulation signal and a first modulation signal to obtain a first control signal so as to control a state of a first transistor on the topology, and performing an AND operation between the pulse width modulation signal and a second modulation signal to obtain a second control signal so as to control a state of a second transistor on the topology. Therefore, the method achieves three topology states and a smooth switchover among the three topology states. In addition, the control circuit is relatively simple, expanding the control scope and improving the control precision. |
