“…The diagram of the current hysteresis controlled PWM is given in Figure 12A. 48,49 In order to understand the hysteresis controlled PWM a single phase inverter with RLE load is taken. When the upper switch of the single phase inverter is ON the current starts increasing and when the currents hits the upper band ðI V Þ in order to decrease the current the lower switch of the inverter is turned on.…”

Use of Pulse Width Modulation (PWM) techniques has enabled the converters to be used in low-frequency high-power applications. The main objectives of PWM are to reduce the line current harmonic, switching energy loss, and torque pulsation and motor acoustic noise (for motor drive applications). This paper mainly deals with selective harmonic elimination PWM (SHEPWM), Hysteresis current controlled PWM (HCPWM), space vector PWM (SVPWM), bus-clamping PWM (BCPWM), and the most advanced wavelet PWM technique (WPWM).

“…Due to the lag of fast timescale information, stability analysis methods have been developed to describe these switching events mathematically, in order to determine the complex phenomena of bifurcations, chaos, and subharmonics [19][20][21]. In addition, studies on the control of power converters from the perspective of switching events have attracted researchers' attentions [22,23]. To address fast-scale nonlinearities, various stability analysis approaches have been applied on the piecewise linear dynamical systems, switched or hybrid systems, such as discrete map-based modeling [19], Floquet theory [24], Lyapunov-based methods [25], and trajectory sensitivity approach [26].…”

Linear Ramp Slope Compensation (LRC) and Quadratic Slope Compensation (QSC) are commonly implemented in peak current mode controlled DC-DC converters in order to minimize subharmonic and chaotic oscillations. Both compensating schemes rely on the linearized state-space averaged model (LSSA) of the converter. LSSA ignores the impact that switching actions have on the stability of converters. In order to include switching events, the nonlinear analysis method based on Monodromy matrix was introduced to describe a complete-cycle stability. Analyses on analogue controlled DC-DC converters applying this method show that system stability is strongly dependent on the change of the derivative of the slope at the time of switching instant. However, in a mixed-signal controlled system, the digitalization effect contributes differently to system stability. This paper shows a full complete-cycle stability analysis using this nonlinear analysis method, which is applied to a mixed-signal controlled converter. Through this analysis, a generalized equation is derived that reveals for the first time the real boundary stability limits, for LRC and QSC. Furthermore, this generalized equation allows the design of a new compensating scheme which is able to increases system stability. The proposed scheme is called Polynomial Curve Slope Compensation (PCSC) and it is demonstrated that PCSC increases the stable margin by 30% compared to LRC and 20% to QSC. This outcome is proved experimentally by using an interleaved DC-DC converter that is built for this work.
