The novel PWM control circuit is able to drive full-bridge based DC–DC converters performing step-down (i.e. buck) and step-up (i.e. boost) voltage conversion in both directions, thus allowing charging and discharging of the batteries in mobile systems. It provides smooth transitions ...

Two possible solutions for eliminating the shoot-through current are: 1. Reduce PWM duty cycle for one PWM period before changing directions.2. Use switch drivers that can drive the switches off faster than they can drive them on. Back to Top0...
are controlled, thereby controlling the transmission direction and leakage inductance current of circuit power, and achieving a smaller current stress and lower circulation loss under the condition of big duty ration and small power seamless switching between operations of the circuit in two directions....
4 wheel mecanum car control movements are fully supported with extended directions like DIRECTION_LEFT, DIRECTION_DIAGONAL_LEFT_BACKWARD, DIRECTION_TURN_RIGHT_IN_PLACE etc.. The motor is mainly controlled by 2 dimensions: Direction / motor driver control. Can be FORWARD, BACKWARD, BRAKE (motor con...
