bootstrap circuit

bootstrap circuit

[′büt‚strap ‚sər·kət]
(electronics)
A single-stage amplifier in which the output load is connected between the negative end of the anode supply and the cathode, while signal voltage is applied between grid and cathode; a change in grid voltage changes the input signal voltage with respect to ground by an amount equal to the output signal voltage.

It also has an inverter gate drive with a bootstrap circuit for high-side power supply, as well as emitter shunts (30 m?
The IC itself consists of all of the necessary power elements (six IGBTs, three pre-drive ICs, and six flyback diodes) needed to configure the main circuit of an inverter, as well as a bootstrap circuit (three bootstrap diodes and three boot resistors) as a highside drive power supply.
An integrated bootstrap circuit for each high side pre-driver requires only an external capacitor.
Additional space savings are realized because the TDA21201 does not require the bootstrap circuit.
An external high-side bootstrap circuit drives the buck switching element at high frequencies up to 500kHz.
