Patent ID: 8723490

Claim:
A control system, comprising: a plurality of control components having inputs coupled to one of a voltage or a current signal received from a bidirectional direct current DC-DC converter, and having an output that provides a compensation control signal based on an analysis of the received voltage or current signal, the plurality of control components comprising: a first boost control component enabled to receive a first voltage signal indicating a high-side voltage of the bidirectional DC-DC converter, compare the first voltage signal to a first preset voltage threshold, and output a first boost control signal to limit the high-side voltage in the bidirectional DC-DC converter if the first voltage signal is greater than the first preset voltage threshold; a second boost control component enabled to receive a second signal related to a positive flow of inductor current in the bidirectional DC-DC converter, compare the second signal to a second non-zero preset threshold, and output a second boost control signal to limit the positive flow of inductor current in the bidirectional DC-DC converter if the second signal is greater than the second non-zero preset threshold; a third buck control component enabled to receive a third voltage signal indicating a low-side voltage of the bidirectional DC-DC converter, compare the third voltage signal to a third preset voltage threshold, and output a third buck control signal to limit the low-side voltage in the bidirectional DC-DC converter if the third voltage signal is greater than the third preset voltage threshold; a fourth buck control component enabled to receive a fourth signal related to a negative flow of inductor current in the bidirectional DC-DC converter, compare the fourth signal to a fourth preset threshold, and output a fourth buck control signal to limit the negative flow of inductor current in the bidirectional DC-DC converter if the fourth signal is greater than the fourth preset threshold; and a duty cycle control circuit having an input coupled to the output of the plurality of the control components, and having an output that adaptively provides a pulse width modulated (PWM) signal that controls a duty cycle of a switch within the bidirectional DC-DC converter, wherein the compensation control signal is utilized to modulate the PWM signal.
