  • the time at which a new control pattern is applied to the outputs can be freely configured. Either updating may be synchronous with changes in the input signals (sensor signals) or asynchronous with the input signals but synchronous with events on the output signals, e.g. with a rising or falling edge at the output, done.

  • FIG. 3 shows a block diagram of an embodiment of the described circuit arrangement, which is denoted overall by the reference numeral 100.
  • the circuit arrangement comprises a timer input module 102, a timer output module 104 with two PWM generators 106 and 108 and a signal evaluation module 110.
  • Three input signals 120, 122 and 124 are input to the timer input module 102. These form the input pattern 125. Together with a validity bit, these are given to the signal evaluation module 110. From this signal evaluation module 110, eight output patterns 130 can be output in dependence on the input pattern 125.
  • the timer output module 104 outputs eight output signals corresponding to the selected output pattern 130, of which the first output signal 132 (channel 0) and the eighth output signal 134 (channel 7) are shown in this illustration.
  • the input signals 120, 122 and 124 on the timer input module 102 come from a BLDC motor and show the current motor position. These are typically three sensor signals.
  • the input pattern or signal pattern 125, that is expected at the inputs has been previously stored by the software in the signal evaluation module 110. Each input pattern 125 is associated with a freely configurable output pattern 130.
  • the output patterns 130 are stored in the signal evaluation module 110 and can be changed by the software at any time. Thus, it is possible to switch the engine operation during runtime.
  • the corresponding output pattern is switched to the outputs of the timer output module 104 or delayed, for example synchronously with an edge of the output signal.
  • Up to eight input and output patterns can be configured.
  • the PWM for one phase is always generated on the same PWM generator (channel 0 of the timer output module 104) and then switched to the corresponding outputs depending on the programmed output pattern 130.
  • the switching can either take place synchronously with the PWM or can be triggered via a further PWM channel (channel 2 of the timer output module 104).
  • a further PWM channel channel 2 of the timer output module 104.
  • Which trigger is used is arbitrary, as this depends on the motor parameters, e.g. the speed or the type of motor depends.
  • the Signalausticianmodul 1 10 reports the corresponding direction of rotation of the motor. If an input pattern 125 is detected which is not programmed or an input pattern 125 is skipped, this signals
  • Signal evaluation module 1 10 with an interrupt to the CPU.
  • the evaluation blocks do not signal the commutation change (such as the Hall sensors, for example), but the zero crossing of the back EMF voltage.
  • This zero crossing is 30 ° (electrical angle) earlier than the next commutation. Therefore, it is necessary in this method to delay the commutation by 30 °. If the signal evaluation module 110 detects a new input pattern 125, the channel 2 of the timer output module 104 is triggered with a so-called NIPD signal. The channel 2 of the timer output module 104 outputs a pulse (OneShot) and thus triggers the next commutation.
  • the CPU must calculate the 30 ° delay and write it to channel 2 of the timer output module 104.
  • the PWM which is always present at one of the outputs, is generated in channel 0 of the timer output module 104.
  • an inverted PWM signal may be generated at channel 1 of the timer output module 104, e.g. To control high and low switches (for example HU + LU) at the same time. This feature is required in some engine operating modes. HU + LU must never be switched on at the same time. To get a safe delay time, the existing triggering mechanism may be used in the channel of the timer output module 104.
  • the Signalausticianmodul 1 10, the timer input module 102 and the timer output module 106 generate the 3-phase AC voltage for the BLDC drive. Depending on an output stage driver, the output signals must be output to three or six timer outputs. The output of the signals is dependent on the input pattern returned by the motor. Two of the three phases for the control are usually switched statically, the third
