Description
Technical field
The invention belongs to the power electronics and the control technology thereof of lighting energy saving engineering, relate to a kind of power conversion circuit of ballast, particularly a kind of power conversion circuit topology and control circuit of electronic ballast of high intensity gas discharge lamp.
Background technology
Electric ballast between power supply and high-intensity gas discharge lamp (HID) gaseous discharge lamp, the whole device that substitutes Inductive ballast, trigger and compensation condenser.Compare with traditional inductance type ballast, electric ballast has advantages such as input power factor height, power conversion efficiency height, prolongation discharge lamp; Also brought simultaneously acoustic resonance, electronic product problem such as functional reliability under adverse circumstances
[1], producing acoustic resonance for fear of ballast, a lot of researchers have done number of research projects.Document [2] has proposed employing hyperfrequency working method, allows lamp be operated in the above frequency of 360kHz, can prevent the generation of acoustic resonance like this.But too high switching frequency easily cause the straight-through up and down of brachium pontis, and efficient reduces.Document [3,4] has been introduced the method for low-frequency square-wave modulation, as shown in Figure 1.When the ripple of square wave less than certain limit, can avoid the generation of acoustic resonance fully.The problem of low-frequency square-wave modulation is to make cost increase greatly owing to use full-bridge circuit that too much power device and complicated control may cause reliability to reduce; And cause transducer effciency to reduce.Document [5] has proposed to utilize the method for white noise modulation, and from experimental result, this method has good effect, but at the ballast that cost is had strict demand, this method is difficult to realize.What document [6] was studied is the sine wave of 400Hz modulation output, also can avoid acoustic resonance, but require under the situation that the dc bus mode is powered.
Electric ballast constant current or permanent power control techniques that document [3,4], [7,8] propose as shown in Figure 3, are by the direct current or the high-frequency ac of sampling HF switch pipe, pass through firstorder filter then, obtain stable output DC stream signal; The output dc voltage signal also is that the discharge lamp terminal voltage is decayed and filtering and obtaining, the stack by two paths of signals so again, and and the power instruction signal relatively, controlled voltage signal, the control that realizes exporting the PWM ripple at last.Permanent power control of the present invention and above-mentioned control technology have fundamental difference, and its two-way voltage and current signal then by links such as filtering, stacks, is realized the control of output PWM ripple from the power frequency ac voltage and the electric current of input.
Document [3,4,7,9,10] has all proposed high-voltage triggering circuit, as shown in Figure 2, all adopts the inductance coupling high mode, rather than the present invention propose transformer coupled, and by the realization of high-pass filtering electric capacity.
Existing patented technology [11] also is a kind of low-frequency square-wave electric ballast output, the two-stage circuit topology, and the present invention is the electric ballast of the sinewave output of one-level circuit topology.Patent [12～14] is that the electric ballast and the difference of the present invention of the high frequency control of two-stage also is conspicuous, and patent [15] adopts mode of frequency regulation to avoid acoustic resonance.

Embodiment
1. power conversion circuit topology
Traditional inductance type ballast adopts the current-limiting apparatus of a frequency inductance as gaseous discharge lamp, and the power factor of its input is low; Output to the terminal voltage instability of discharge lamp, seriously shortened the life-span of discharge lamp.The electronic ballast of research is in order to obtain High Power Factor at present, and front end all adds a circuit of power factor correction, and by stable voltage of half-bridge converter output or electric current, therefore, has overcome the deficiency of inductance type ballast significantly.Shortcomings such as but the shortcoming of bringing is a Power Conversion has adopted two-layer configuration, and it is low to cause changing efficient, and control is complicated, and reliability is low.For this reason, in order to overcome these shortcomings, the power conversion circuit topology of electronic ballast of high intensity gas discharge lamp of the present invention as shown in Figure 5.
Filter among the figure is the present essential EMC interface circuit of all electronic ballasts, and switching tube V1, V2 are connected as figure with V3, V4, have constituted two groups of two-way gate-controlled switches respectively, and have had drivingly public; L2 is the high frequency ballast inductance of high-intensity gas discharge lamp Lamp.Switching tube V1 and V2 are operated in high frequency (25KHz) on-off mode.When the input line voltage was positive half cycle, V4 always was in conducting state.When V1 and V2 conducting simultaneously, V3 ends, and the inductive current direction is to flow to Lamp; When V1 and V2 turn-offed, the inverse parallel diode current flow of V3 inside provided the freewheel current of inductance L 2.When the input line voltage was negative half period, V3 always was in conducting state.When V1 and V2 conducting simultaneously, V4 ends, and the inductive current direction is to flow back to from Lamp; When V1 and V2 turn-offed, the inverse parallel diode current flow of V4 inside provided the freewheel current of inductance L 2.In order to improve the efficient of converter, when the inverse parallel diode operation of V3 or V4 inside, V3 or V4 are operated in the synchronous rectification state.
The Buck circuit of this circuit and standard is distinguishing, and at first the Buck circuit is the direct current input, and secondly the Buck circuit must have output capacitance.
But output voltage u at any time,
