Analysis of bipolar PWM schematic diagram
Bipolar PWM mode Bipolar PWM control mode uses positive and negative alternating bipolar triangular carrier UT and modulation wave ur, as shown in Fig. 6.3. Bipolar PWM pulse can be directly obtained by comparing UT and ur, without phase inversion circuit.
1.5 kW PWM Bipolar Inverter
 · PDF 檔案In a bipolar PWM inverter, the output switches between +Vdc and -Vdc. The switches sl and s2 turn on, and switches s3 and s4 turn off, when the amplitude of the sinusoidal control signal is greater than the amplitude of the triangle carrier signal. For a unipolar
Universal Bipolar PWM Driver 1 (UBPD1)
The Demo version outputs signals on the PWM pins that are similar to the “real” versions, as well as pulsing “Up” and “Down” LEDs monitoring the knob rotation. But the firmware architecture is totally different. So, I’m not sure what it’s really good for. 😉

Bipolar switching is compatible with BLDC drivers. See Figs 10 and 12 in the eFlexPWM application note. Consider that since PWM frequencies are higher than the motor’s response time, the PWM’ing is effectively creating an average voltage.

Bipolar PWM and LCL Filter Configuration to Reduce …

Bipolar Pulse Width Modulation (BPWM) technique along with filter L-C-L configuration in the circuit is modeled to shrink the leakage current in the circuit. The DC/AC inverter is modeled using H-bridge Insulated Gate Bipolar Transistor (IGBT) module which is controlled using proposed Bipolar PWM …
Insulated-gate bipolar transistor
An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch, which, as it was developed, came to combine high efficiency and fast switching. It consists of four alternating layers (P–N–P–N) that are controlled by a metal–oxide–semiconductor (MOS) gate structure

 · PDF 檔案LV8127T is a three-phase bipolar PWM drive pre-driver IC for N-channel High-side and Low-side FETs. This IC is optimized for low cost, high-efficiency drive circuits in applications that use motors with high drive currents. It offers high supply voltage capability and
Pulse-width modulation
Pulse width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power delivered by an electrical signal, by effectively chopping it up into discrete parts.The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast rate.
