IGBT-based pulse voltage generator which can produce high voltage square wave and PWM waveforms has been successfully developed in this research. The generator consists of IGBT switches and other wave shaping components. The special cascade connection circuit design enables the generator to produce the stable

2017年8月7日 · A high voltage pulse generator based on a silicon-controlled rectifier has been designed and implemented for a field reversed configuration experiment. A critical damping circuit is used in the generator to produce the desired pulse waveform.

A twelve pulse synchronized pulse generator is used to generate the twelve synchronized gate pulses for triggering the 12 thyristors used in 12- pulse convertor. The pulse generator is synchronized with the load current and the firing angle of the

12-pulse diode rectifier results in the cancellation of the fifth and seventh harmonics in the input utility line currents, and the kVA rating of the transformer is

The 12-pulse rectifier is made up of 2 6-pulse AC-DC bridge, each 6-pulse AC-DC has a 3 phase input which have 30 degree phase error between the 2 bridges. • Better PF and THDi than 6-pulse • Easy to control and realize. • Big size and low efficiency

Trigger pulses of three-phase rectifier are generated by the pulse power amplifier circuit. Four of the output pulses are shown in Fig. 7. It is triggered by double-narrow pulse, pulse...

We want to simulate a single-phase half-wave thyristor rectifier with an RL load (R=10 Ω and L= 10 mH). The model of this example is shown in Figure 5-1. This model uses Thyristor (see Figure 5-2) and Pulse Generator (see Figure 5-3) blocks. Input AC source has a peak of 169.7 V and frequency of 60 Hz.

SPWM technique is used for providing triggering pulse to the rectifier and inverter. It is very accurate method as it concern with the modulation of the amplitude and frequency. By changing modulation index (Ma) output of voltage and current amplitude can be controlled.

where α is firing angle in degree, by changing the firing angle you can get different voltage output from Single-phase rectifier. As we know standard frequency is 50Hz. so, time required to complete one cycle is (t=1/50Hz=0.02 sec.).
