In this paper induction heating system is modeled and effective factors on induction heater system losses are represented. Respective to the intensive importance of capacitor losses and its potential ability of being harmful, furnace parameters must be designed in a way to minimize capacitor losses and maximize the transmitted power into the load. The effective parameters are the number of turn...

This paper presents two novel active-feedback single Miller capacitor frequency compensation techniques for low-power three-stage ampli ̄ers. These techniques include the active-feedback single Miller capacitor frequency compensation (AFSMC) and the dual active-feedback single Miller capacitor frequency compensation (DAFSMC). In the proposed techniques, only one Miller capacitor in series with a...

This work focuses on the estimation of the Remaining Useful Life (RUL) of aluminum electrolytic capacitors used in electrical automotive drives under variable and nonstationary operative conditions. The main cause of the capacitor degradation is the vaporization of the electrolyte due to a chemical reaction. Capacitor degradation can be monitored by observing the capacitor Equivalent Series Res...

This paper demonstrates the phase imbalanced series capacitive compensation concept to enhance power system dynamics as it has the potential of damping power swing as well as sub synchronous resonance oscillations. A scheme for a phase imbalanced capacitive compensation is shown. It is a “hybrid” series compensation scheme, where the series capacitive compensation in one phase is created using ...

A compact and sharp rejection UWB microstrip bandpass filter is developed using of left handed metamaterials. For realizing a backward-wave propagation medium, two split ring resonator (CSRR) in the back substrate side and also one series capacitor etched in the host line, are used to produce a negative effective ε and μ, simultaneously. Moreover, two doublets parallel coupling gaps is placed a...

This paper discusses power flow control by use of controllable series devices. Through a sensitivity based method the control variables, e.g. series capacitor reactances or phase shifter angles, can be calculated quickly and accurately to obtain desired line flows within the load flow sensitivity boundaries. This method is applied to realistic power flow control scenarios in a simple power system.
