[EVDL] Regen on AC Inverter

In order to accomplish regen with an AC inverter on an all electric vehicle are the IGBTs modulated or is a buck boost circuit added to the inverter? -- next part -- An HTML attachment was scrubbed... URL:

Re: [EVDL] Regen on AC Inverter

I can conclude from what you say that during regen mode none of the IGBTs are energized. Therefore, only during drive operation are the IGBTs switched. Since the car is slowing down during deceleration, the motor RPMs are decreasing. At some point, the voltage generated by the motor will dro

Re: [EVDL] Wheel Speed Sensor

First some criticisms: (1) About three weeks ago I posted a question "How does regenerative braking work" No one had an answer. Now numerous people appear to know something about regenerative braking. (2) My original question was "has anyone installed a wheel speed sensor on an EV conversion

Re: [EVDL] Wheel Speed Sensor

Corbin, a braking resistor is typical for industrial variable frequency drives (VFD) and older SCR drives. A VFD connected to a utility service is usually not allowed to regen into the line. As an example. If one installs a VFD on a large rotating mass such as a molder. When the mold breaks

[EVDL] Regen and Smart Cruise Control

I noticed a series of e-mails on regen and smart cruise control. These two topic are closely related. I have been looking at implementing regen on an AC motor controller. I found that designing an AC motor controller in simple comparison to selecting the best regen implementation. There are
