Generalized half-bridge and full-bridge resonant converter topologies with two, three and four energy storage elements are presented. All possible circuit topologies for such converters under voltage/current driven and voltage/current sinks are discussed. Many of these topologies have not been investigated in open literature. Based on their circuit
Step 1. A circuit consists of switches that open or close at t = 0, resistances, dc sources, and a single energy storage element, either an inductance or a capacitance. We wish to solve for a current or a voltage (t) as a function
The purpose of an opening switch is simply to stop the flow of current in the circuit branch containing the switch. Prior to this action, of course, the opening switch must first conduct the current as required--that is, operate as a closing switch.
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
The advantage of utilizing the switch-mode is that the switching and conduction losses can be minimized by increasing the switching frequency. energy storage elements, load conditions and so on. Many control topologies have been proposed in the literature to control series resonant converters, for instance, the current and
It is common to choose the energy storage elements as the state of the system, which is current for inductors and voltage for capacitors. It is noted irrespective of charging or discharging, that is buck or boost, as the switches Q1 and Q2 are complimentary to each other and there are only two sub-intervals:

Since energy storage components charge and discharge with respect to time the circuit network will react and relax relative to these changes according to the (relaxation) time constants associated with the L and C components. The mathematics of the charge and discharge of energy storage elements are defined by equations (3.5-1) and (3.5-3).
Abstract. The purpose of an opening switch is simply to stop the flow of current in the circuit branch containing the switch. Prior to this action, of course, the opening switch must first conduct the current as required--that is, operate as a closing switch. To accomplish current interruption, the opening switch must force the current to

The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor. Large values give maximum power output and low output
A novel and general approach is proposed that consists of three matching principles, which enables one to assign a best set of energy storage elements to a DC/DC converter to meet both desirable
This solution is the forced response, xf(t). Represent the response of the second-order circuit as x(t)=xn(t) + xf(t).
